1.0 Introduction

1.1 Background

1.1.1 This statement is prepared on behalf of the London Organising Committee of the Olympic and Paralympic Games (LOCOG) and the Olympic Delivery Authority (ODA). The statement is submitted in support of the planning applications for the Eton Dorney Olympic and Paralympic venue, which will host Olympic Rowing and Canoe Sprint events and Paralympic Rowing events.

1.1.2 The Eton Dorney venue falls within the administrative boundaries of two Local Authorities, namely South District Council (SBDC) and Royal Borough of Windsor and (RBWM). The site also falls within the boundaries of Buckinghamshire County Council (BCC). For the purposes of these planning applications, the venue comprises , Windsor Racecourse and the as the three principal components.

1.1.3 This submission consists of five planning applications which comprise the following:

• Planning application for the Temporary Pedestrian River Crossing submitted to SBDC;

• Planning application for the Temporary Pedestrian River Crossing submitted to RBWM;

• Planning application for the Olympic Transport Hub at Windsor Racecourse submitted to RBWM;

• Planning application for Eton Dorney Rowing Lake overlay submitted to SBDC; and

• Planning application for the Variation of Condition 15 of planning permission SBD/8201/05, submitted to BCC.

1.1.4 The full Descriptions of Development for the individual applications are set out within the supporting Planning Statement and on the relevant planning application forms.

1.1.5 This statement relates to the Eton Dorney venue and has been prepared for submission in support of each of the individual planning applications.

1.1.6 On 6 July 2005 the International Olympic Committee (IOC) awarded the 2012 Olympic and Paralympic Games (“2012 Games”) to London. The ODA is the public London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

body responsible for developing and building the new venues and infrastructure for the 2012 Games and LOCOG is responsible for preparing and staging the Games, including the temporary venues and overlay.

1.1.7 Eton Dorney was selected as the venue for Olympic Rowing and Canoe Sprint events and Paralympic Rowing Events, as part of the “London Bid” for the Games.

1.1.8 London 2012 is required to apply for planning permission for operations and changes in use of land for the London 2012 Olympics and Paralympic events that constitute development requiring planning permission. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

1.1. Cultural Heritage

Context

1.1. Oxford Archaeology (OA) have been jointly commissioned by the London Organising Committee of the Olympic and Paralympic Games (LOCOG) and the Olympic Delivery Authority (ODA) to carry out an cultural heritage asset desk-based assessment for the Eton Dorney Venue. The location of these sites is shown on Figure 4.1. For the purposes of this report the assessment of the Dorney Lake includes the Paralympic Transport Hub (PTH) as within the area of the Site. The assessment of the Olympic Transport Hub is included within the section dealing with the Racecourse Site.

1.2. LOCOG and the ODA propose to construct a number of temporary facilities at the Eton Dorney Venue in order to accommodate the 2012 Games. These proposals are set out in detail in the Design and Access Statement.

1.3. The aim of this project is:

• to provide an assessment of the cultural heritage potential of the sites;

• to describe the impacts of previous development on the survival of any archaeological remains and historic landscape assets;

• to assess the impact of the proposals on the surviving cultural heritage assets including any settings issues; and

• to present proposals for the most likely strategy for the mitigation of any such impacts defined.

1.4. This chapter is supported by:

• Appendix 4A - a list of sources and references;

• Appendix 4B - a gazetteer of all identified cultural heritage assets referred to; and

• Five figures - numbered 4.1 to 4.5, showing the location of the sites, the detailed local geology, identified assets in a 1km study area, a detailed features map of the Lake site and previous impacts to the Lake site.

1.5. Location, Geology and Topography London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

1.6. The Eton Rowing Course site lies on the north bank of the river Thames between the village of Dorney and the hamlet of , some 2.5 km west of Eton (Figure 4.1). The Rowing Course and Return Lane were constructed between 1996 and 2006 on land owned by , and lie on a north-west to south-east alignment, the Start End being at the north-west, and the boathouse at the Finish End.

1.7. The geology of the Eton Rowing Course consists of Drift deposits of Pleistocene gravels over London Clay (BGS sheet 269; Windsor, Solid and Drift 1981; 1999; Figure 4.2). The area is shown simply as `alluvial gravels’ on the 1981 edition, and (again without subdivision) as `mainly silt and clay’ on the 1999 edition. These have left behind deep deposits of waterlain clays, peat deposits and alluvial silts, hence the description as `mainly silt and clay’. The geology of the Windsor Racecourse site is recorded on both the 1981 and the 1999 edition maps as alluvium (BGS sheet 269; Windsor, Solid and Drift, 1981; 1999).

1.8. Prior to the construction of the Rowing Course the ground sloped gently from north- west to south-east, with dips corresponding to the location of the former basins and channels. The Racecourse site is essentially flat, although a very slight slope is evident from west to east, east of the Marina.

1.9. The Detailed Geology of the Eton Rowing Lake Course

1.10. As the previous archaeological investigations have shown, the varying geology significantly affects the character of archaeological remains across the Lake site and the Racecourse site. Cropmarks are only visible on the gravel terrace deposits, due to the increased water-retention of the alluvial deposits in the basins and their obscuration of earlier features. Archaeological features dug below the ground, such as pits and ditches, occur predominately, though not exclusively, on the higher and drier gravel terraces, due to the relatively high water table. Surface occupation horizons and features such as hearths, in contrast, only survive on the floodplain, where protected from ploughing by a deep covering of alluvium. The deeper parts of the basins contain preserved peat deposits, while the former channels contain both waterlogged peats and other fluvial deposits, within which were found preserved wooden structures and other artefacts.

1.11. The geology of the Rowing Course has been investigated in detail and it is considered highly likely that similar geological conditions underlie the Racecourse site. A detailed understanding of the origins and extent of these deposits was established during construction of the Rowing Course (see section 3.1.1 and Figure 4.2). A levels survey of the Eton Rowing Course site was carried out prior to London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

construction, and this has also been used to assist in establishing the geological make-up of the site.

1.12. The gravel terrace deposits directly underlie the modern topsoil at the west and east ends of the Rowing Course site, although the gravel is cut through by a former loop of the Thames (labelled Channel T and V on Figure 4.2), separating an area of gravel in the centre of the Rowing Course development area. There was also a triangle of gravel (labelled Terrace X) in the centre of the Site, west and east of which were broad basins, Basin R and Basin W. The north part of Basin R was only investigated by limited archaeological evaluation trenching, but these were sufficient to determine the general sequence (OA 1995, 3.2.3 and 3.2.4 and Figures 4 and 5). Evaluation of the field west of the boundary was limited to the south-east end, and these trenches revealed more than 2 m of waterlain deposits, but were not bottomed. On the south side Basin R was investigated both by evaluation and by excavation areas Ex1-3 (OA 1995, 3.2.4, Figure 5; Allen and Welsh 1996-98). Here the sequence of deposits was similar to that on the north, but the basin was shallower and the deposits correspondingly thinner.

1.13. Basin R was originally a lake basin in the Early Holocene, but which silted up gradually, filling with deposits of clay, reed bed peat and later alluvium, and had become seasonally dry floodplains by the Neolithic (4000 BC). Basins R and W were linked by a former channel cut between Terrace X and the main central gravel island, and their silting sequence was similar. Basin W was only investigated by evaluation trenches, but enough were dug to establish the general sequence of infilling (OA 1996, 4.2 and 4.3 and Figures 3 and 4). As in Basin R, Basin W was deepest on the north, and became shallower to the south-east.

1.14. A former major channel of the river Thames, Channel T, flowed west to east through the middle of Basin R (OA 1995, 3.2.4 and Figure 5). This was investigated by area excavations in areas Ex1 and Area 3 (Allen and Welsh 1996), in Areas 1, Ex2 and 5 (Allen and Welsh 1997), and in Areas Ex3, 16 and 14 (Allen and Welsh 1998), although the high water table meant that the base of the channel was not reached. At the east edge of the Eton Rowing Course development area Channel T met and cut into another former major channel that ran south-east down the eastern limit of the development area. The Cress Brook follows the line of this former channel, and historic maps show that it continued to flow (though much reduced) into the 20th century. This area was investigated by numerous evaluation trenches, and by excavations in Areas 3 and 5, with Watching Brief in between (OA 1995, 3.2.6 and 3.2.7, and Figures 7 and 8; OA 1996, 7.3 and Figure 14; Allen and Welsh 1996, 1997 and 1998). London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

1.15. East of Area 3 the Thames palaeochannel and the Cress Brook channel divided again, the Cress Brook channel continuing eastwards north of Boveney and rejoining the Thames south of , while the Thames palaeochannel (Channel V) turned south and rejoined the modern Thames just west of Boveney. No evaluation trenches were dug within the Rowing Course site here, but trenches dug further north, plus area excavation on the west (Area 4) and east (Area 6) sides, allow the sequence to be characterised (OA 1996, 4.8 and Figure 9; Allen and Welsh 1997).

1.16. The gravel terrace surrounded by the loop of the Thames palaeochannel (Channels T and V) had been cut through by yet another ancient palaeochannel, which had later been blocked by further gravels and sands, leaving an open channel downstream of the blocking (labelled Inlet Z). Inlet Z was investigated both by evaluation trenches and by excavation in Area 15 and Area 4. It first filled with pale silts and clays, which were washed away on the west side by a deeper channel that gradually silted up with waterlogged sands overlain by deep peat deposits of Mesolithic and Neolithic date, overlain at the top by alluvial deposits containing Iron Age and Roman finds (OA 1996, 4.8.11-14 and Figure 9; Allen and Welsh 1997; Parker and Robinson 2003).

1.17. A smaller palaeochannel (Channel S on Figure 4.2) ran south from the Cress Brook channel at the north corner of the Rowing Course development area, and then ran south-east to join Channel T at the north end of Basin R. This channel was still accumulating peat into later prehistory (OA 1995, 3.2.5 and Figure 6), but had silted up before the Roman period. Prior to the construction of the Rowing Course the ground sloped gently from north-west to south-east, with dips corresponding to the location of the former basins and channels.

1.18. Sources Consulted

1.19. The data used in this assessment was originally collected and collated in 2002 for a previous study and has been supplemented by further searches in both 2007 (OA 2002; OA 2008) and 2010 for this assessment The following sources were updated where necessary and expanded to include the larger Study Area in preparing this assessment:

• The Buckinghamshire Heritage Environment Record (Bucks HER; held by Buckinghamshire County Council);

• The Heritage Environment Record (held by Berkshire Archaeology);

• The National Monument Record (NMR; held by English Heritage); London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

• The National Aerial Photographic Collection held by English Heritage at the NMR in Swindon and the Aerial Photographic collection held by the University of Cambridge;

• The Buckinghamshire HER was visited in 2007 and 2010 in order to examine additional aerial photographs held of the Eton Rowing Lake and the Racecourse;

• The Buckinghamshire Record Office, Aylesbury; and

• The Berkshire Record Office, Reading.

1.20. The Bucks HER, the Berks HER and the NMR supplied digital data on all known sites and events within a 1km Study Area surrounding the sites (Figure 4.3). A walkover survey of the sites was undertaken by OA on the 15th of April 2010. The objectives of the survey were to:

• Confirm the presence/absence of previously known heritage assets (‘ground- truth’);

• Identify potential new heritage assets;

• Identify areas where survival may be compromised;

• Identify potential impacts to the setting of the built heritage within and close to the sites; and

• Record the land use of the sites and the nature of extant boundaries.

1.21. Appendix 4A is a gazetteer of identified heritage assets within the 1km Study Area. Each entry has been allocated an OA number, added to the gazetteer, and marked on Figures 4.3 and 4.4, where appropriate. A full list of sources consulted can be found in Appendix 4B.

2.0 Planning Context

2.1. National Guidance

2.2. Planning Policy Statement 5: (PPS5) Planning for the Historic Environment (issued March 2010) sets out the Government’s planning policies on the conservation of the historic environment and the rationale for its conservation. The policy takes a holistic approach to the historic environment, identifying all elements within this environment that are worthy of consideration in planning matters as ‘heritage assets’. A heritage asset is identified by PPS5 as an environmental component that holds meaning for society over and above its functionality. This term includes buildings, parks and gardens, standing, buried and submerged remains, areas, sites and landscapes, whether designated or not and whether or not capable of designation.

2.3. Policy HE3 states: ‘3.1 Regional spatial strategies (RSS) and local development frameworks (LDF) should set out a positive, proactive strategy for the conservation and enjoyment of the historic environment in their area, taking into account the variations in type and distribution of heritage asset, as well as the contribution made by the historic environment by virtue of:

• its influence on the character of the environment and an area’s sense of place;

• its potential to be a catalyst for regeneration in an area, in particular through leisure, tourism and economic development

• the stimulus it can provide to inspire new development of imaginative and high quality design

• the re-use of existing fabric, minimising waste; and

• its mixed and flexible patterns of land use that are likely to be, and remain, sustainable.

• ‘HE 3.2 The level of detail contained in an RSS or LDF should reflect the scale of the area covered by the plan and the significance of the heritage assets within it.’

2.4. ‘HE 3.3 At a regional level, the character and significance of the historic environment should inform the RSS with particular attention paid to the landscapes and groupings or types of heritage assets that give distinctive identity to the region or areas within it. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

Some individual heritage assets such as World Heritage Sites are likely to have regional significance in plan-making.’

2.5. ‘‘HE 3.4 At a local level, plans should consider the qualities and local distinctiveness of the historic environment and how these can contribute to the development of the spatial vision in the local development framework core strategy. Heritage assets can be used to ensure continued sustainability of an area and promote a sense of place. Plans at a local level are likely to consider investment in and enhancement of historic places, including the public realm, in more detail. They should include consideration of how best to conserve individual, groups or types of heritage assets that are most at risk of loss through neglect, decay or other threats (see also policy HE50).’

2.6. ‘HE7.2 In considering the impact of a proposal on any heritage asset, local planning authorities should take into account the particular nature of the significance of the heritage asset and the value that it holds for this and future generations. This understanding should be used by the local planning authority to avoid or minimise conflict between the heritage asset’s conservation and any aspect of the proposals.’

2.7. ‘HE7.3 If the evidence suggests that the heritage asset may have a special significance to a particular community that may not be fully understood from the usual process of consultation and assessment, then the local planning authority should take reasonable steps to seek the views of that community.’

2.8. ‘HE7.4 Local planning authorities should take into account:

• the desirability of sustaining and enhancing the significance of heritage assets, and of utilising their positive role in place-shaping; and

• the positive contribution that conservation of heritage assets and the historic environment generally can make to the establishment and maintenance of sustainable communities and economic vitality by virtue of the factors set out in HE3.1.’

2.9. HE7.5 Local planning authorities should take into account the desirability of new development making a positive contribution to the character and local distinctiveness of the historic environment. The consideration of design should include scale, height, massing, alignment, materials and use’

2.10. HE7.6 Where there is evidence of deliberate neglect of or damage to a heritage asset in the hope of obtaining consent, the resultant deteriorated state of the heritage asset should not be a factor taken into account in any decision.’ London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

2.11. ‘HE7.7 Where loss of significance is justified on the merits of new development, local planning authorities should not permit the new development without taking all reasonable steps to ensure the new development will proceed after the loss has occurred by imposing appropriate planning conditions or securing obligations by agreement.’

2.12. Policy HE12 states: ‘HE12.1 A documentary record of our past is not as valuable as retaining the heritage asset and therefore the ability to record evidence of our past should not be a factor in deciding whether a proposal that would result in a heritage asset’s destruction should be given consent.’

2.13. ‘HE12.2 The process of investigating the significance of the historic environment, as part of plan-making or development management, should add to the evidence base for future planning and further the understanding of our past. Local planning authorities should make this information publicly available, including through the relevant historic environment record.’

2.14. ‘HE12.3 Where the loss of the whole or a material part of a heritage asset’s significance is justified, local planning authorities should require the developer to record and advance understanding of the significance of the heritage asset before it is lost, using planning conditions or obligations as appropriate. The extent of the requirement should be proportionate to the nature and level of the asset’s significance. Developers should publish this evidence and deposit copies of the reports with the relevant historic environment record. Local planning authorities should require any archive generated to be deposited with a local museum or other public depository willing to receive it. Local planning authorities should impose planning conditions or obligations to ensure such work is carried out in a timely manner and that the completion of the exercise is properly secured’.

2.15. Local Guidance

2.16. The South-East Plan

2.17. The South East Plan was the Regional Spatial Strategy for the South East. It was revoked by the Secretary of State for Communities and Local Government on 6 July 2010.

2.18. Buckinghamshire County Structure Plan 1991-2011: Saved Policies London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

2.19. Policy HE 1: Protection of key sites and features. ‘Permission will not be given for any development which would endanger, or have a significant adverse effect on the character or appearance and/or setting of any of the following:

• Listed Buildings;

• Scheduled Ancient Monuments and other important archaeological sites;

• Historic Parks or Gardens;

• Conservation Areas.

2.20. Policy HE 1: ‘Proposals, which would lead to the enhancement of any of these features, will generally be encouraged provided that there is no significant conflict with any other relevant policies in this Plan.’

2.21. : Local Plan

2.22. The Council is preparing the South Bucks Local Development Framework. The Local Development Framework will guide the planning of the District to 2026. However, as this is in the early stages of preparation, consideration needs to be given to the Local Plan.

2.23. The Government Office for the South East issued a Direction under paragraph 1(3) of Schedule 8 to the Planning and Compulsory Purchase Act 2004, on 25 September 2007, to SAVE the following policies of the South Bucks Local Plan 1999 (until they are replaced by policies in a new Development Plan).

2.24. These policies are:

• C1 - Development within a Conservation Area;

• C6 - Alterations and Extensions to Listed Buildings;

• C13 - Nationally Important Archaeological Remains; and

• C14 - Other Archaeological Remains.

2.25. Policy C 13 states: ‘Development will not be permitted which is likely to cause demonstrable harm to a site of, or the setting of, nationally important archaeological remains, whether Scheduled or not. When assessing applications affecting nationally important archaeological remains the Council will have regard to the following factors: London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

• the results of evaluation by fieldwork;

• the impact of the proposed development on the archaeological remains;

• measures to mitigate the impact of the proposed development; and

• whether any of those measures can and need to be secured by the imposition of conditions or by legal agreement.’

2.26. Policy C 14 states: ‘When assessing proposals affecting other archaeological remains the Council will have regard to the following:

• the results of evaluation by fieldwork;

• the impact of the proposed development on the archaeological remains;

• measures to mitigate the impact of the proposed development; and

• whether any of those measures can and need to be secured by the imposition of conditions or by legal agreement.’

2.27. ‘Where in-situ preservation is merited development which is likely to cause demonstrable harm to the site or its setting will not be permitted. Where the Council is minded to grant permission for development which would involve the destruction of remains, archaeological investigation and recording of evidence will be required prior to the commencement of and during, the development.’

2.28. The Royal Borough of Windsor and Maidenhead Local Plan: Saved Policies 2007

2.29. The Government Office for the South East issued a Direction under paragraph 1(3) of Schedule 8 to the Planning and Compulsory Purchase Act 2004, on 27 September 2007, to SAVE the following policies of the RBWM Plan 203 (until they are replaced by policies in a new Development Plan).

2.30. These policies are:

• CA1 - Development in Conservation Areas;

• CA2 - Guidelines on Development Affecting Conservation Areas;

• CA6 - Car Parking in Conservation Areas; London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

• LB2 - Proposals affecting Listed Buildings or their Setting;

• LB3 - Change of Use of Listed Buildings;

• HG1 - Historic Gardens and Formal Landscape;

• ARCH1 - Development on Scheduled Ancient Monuments;

• ARCH2 - Sites of Archaeological Importance;

• ARCH3 - Sites of Archaeological Importance; and

• ARCH4 - Sites of Archaeological Importance;

2.31. Policy ARCH1 states: ‘There will be a presumption in favour of the preservation of scheduled and nationally important monuments and their settings. Planning permission will not be granted for any development likely to affect the preservation of such monuments and their settings.’

2.32. Policy ARCH2 states: ‘Planning permission will not be granted for proposals adversely affecting sites in Berkshire's sites and monuments record where archaeological features merit in situ preservation unless it can be demonstrated that:

1) The Proposals will not harm the archaeological importance of the site and its setting;

2) Appropriate and acceptable provision is made for the protection and management of the archaeological remains in situ prior to and/or during development.’

2.33. Policy ARCH3 states: ‘Planning permission will not be granted for proposals which appear likely to adversely affect archaeological sites and monuments of unknown importance and areas of high potential unless adequate evaluation enabling the full implications of the development on matters of archaeological interest is carried out by the developer prior to the determination of the application.’

2.34. Policy ARCH4 states: ‘Planning permission will not be granted for proposals which appear likely to adversely affect archaeological sites and monuments of unknown importance and areas of high potential unless adequate evaluation enabling the full implications of the development on matters of archaeological interest is carried out by the developer prior to the determination of the application .’ London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

3.0 The Recorded Cultural Heritage Resource

3.1. Designated Cultural Heritage Assets

3.2. There are no Cultural Heritage Designated Sites within the secure perimeter for either the Lake or Racecourse sites. The nearest Designated assets are a cluster of Listed Buildings in the core of the historic village of Boveney, immediately to the north of the Lake site, and a Grade I Listed redundant church. The Listed Buildings in Boveney comprise one Grade I structure (the later medieval church) and eight Grade 2 structures dating from between the 16th and 18th centuries (Figure 4.3).

3.3. Introduction to previous archaeological work (Figure 4)

3.4. No recorded archaeological activities have been identified from within the area of the Racecourse site.

3.5. The extensive recorded assets described below principally derived from various archaeological interventions on the Lake site that were undertaken in advance of the construction of the current facilities. The construction of the current facilities will thus have, in many cases, removed much if not all of the archaeological deposits from which these discoveries were made.

3.6. The first significant study of the Rowing Lake site was by Carstairs, who studied cropmarks and fieldwalked the site in 1986. OA acted as consultants to Eton College in preparing the planning application for the Eton Rowing Course from 1987, conducting evaluations in 1987 and 1990 (some trenches from which are in the ODA site), and represented the college on archaeology at the planning enquiry. Eton obtained consent in 1993, and OA conducted further evaluation in 1994 and 1995. The further evaluation covered most of the ODA site. Archaeological excavations in advance of the construction of the Rowing Course were carried out in 1995-7, 1999 and 2000. The width of the Return Lane was revised in 2001-2, leading to further excavation in 2003. A last Watching Brief was carried out in 2004.

3.7. The evaluations and excavations revealed a complex and changing past landscape within and around the Lake site, with significant remains of every period from Mesolithic (9000-4000 BC) to Anglo-Saxon (AD 410-1066). It is important to note that apparent paucity of archaeological sites and finds from the Racecourse site reflects the low level of archaeological interventions rather than a low archaeological potential. The Racecourse site sits in a similar riverside location in the local landscape and it is very likely that the Racecourse site also contains significant but currently unrecorded archaeological deposits. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

3.8. The geology significantly affects the character of archaeological remains across the site. Cropmarks are only visible on the gravel terrace deposits, due to the increased water-retention of the alluvial deposits in the basins. Archaeological features dug below the ground, such as pits and ditches, occur predominately, though not exclusively, on the higher and drier gravel terraces, due to the relatively high water table. Surface occupation horizons and features such as hearths, in contrast, only survive on the floodplain, where protected from ploughing by a deep covering of alluvium. The deeper parts of the basins contain preserved peat deposits, while the former channels contain both waterlogged peats and other fluvial deposits, within which were found preserved wooden structures and other artefacts.

3.9. Not all of the evidence can be pinpointed to discrete archaeological `sites’, but belongs to zones of activity of various types. Similarly, the channel and floodplain areas contain a wide variety of environmental evidence of past environments, but although these were sampled at specific points during the archaeological investigations for the Rowing Course, they are not confined to these locations. The gazetteer indicates the key archaeological discoveries (indicated in the text below by numbers prefixed by OA, and on plan by dots with the numbers only on Figure 4.3, with more detail on Figure 4.4), but there were many lesser deposits of archaeological material that are not individually numbered, as this would simply have confused the mapping of the evidence. For some gazetteer entries discoveries of several periods were made in close proximity, and these are indicated on plan by a gazetteer number followed by a letter, eg. 14A, 14B, each colour-coded by chronological period.

3.10. Palaeolithic and Mesolithic (500,000 - 4,000 BC)

3.11. The Wider Study Area (Figure 4.3)

3.12. Three Palaeolithic finds have been made within the Wider Study Area. These comprised a flint implement found at Dorney (OA 161) 1.2 km north-west of The Lake and two handaxes; one found to the south of (OA 165) 1.8km north-west of The Lake and the other in a garden in Dedworth (OA 279) some 750 metres south- east of The Racecourse.

3.13. Six Heritage Assets dating from the Mesolithic have been recorded in the Wider Study Area. A large number of struck flints (OA 5) were found in a back garden on the opposite bank to The Lake in the late 1970s (Wymer 1977). Two pebble `maceheads’ of Mesolithic type, together with flint blades and deer bones, were found in Prior’s pit, Water Oakley, some 220 metres to the south-west of The Lake (OA 52A) during London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

gravel extraction (Ford 1987, 59). The frontal portion of a highly mineralised skull (OA 110) was recovered from the Thames near to Monkey Island 280 metres to the north- west of The Lake, while two flint assemblages (OA 115) have been recovered at Weir Bank Stud Farm and Water Oakely some 640 metres to the north-west of The Lake. A number of Tranchet axes (OA 230) have been found at , on the opposite bank of the Thames to The Racecourse, while mixed finds have been recovered from sites at Boveney (OA 239) around 40 metres north-east of The Lake and at Water Oakley, 150 metres to the south-west of it.

3.14. Two possible Late Upper Palaeolithic finds were made within the area of the Rowing Lake. These comprised two flint blades from evaluation Tr. 165 (OA 1). Early Mesolithic struck flints were found in three locations on the gravel terrace, in the top of a periglacial swallow hole in Area 24 (OA 2), close to Channel S in Area 20 (OA 3) and in Trenches 173 and 165 on the edge of Basin R (OA 4). Further finds made along the gravel terrace here during archaeological evaluation (OA, 1995) suggest that there may have been temporary along this stretch of the river.

3.15. Later Mesolithic activity was more widespread, but was on a much smaller scale. Along the levees (banks) of the former Thames channel in Trench 169, on Terrace Y, in Area 5 and Area 6 small clusters of struck flints show temporary encampments (OA 6-9), and tree-holes were used as shelters for tool manufacture while hunting (OA 10). An antler mattock was found on the levee in Ex3 (OA 11A), and a stone weight in Area 14 (OA 12).

3.20. Neolithic (4,000 BC - 2400 BC)

3.21. The Wider Study Area (Figure 4.3)

3.22. Eight Heritage Assets have been identified within the wider Study Area. A mortuary enclosure has been identified at South Field, Eton Wick (OA 222), around 150 metres to the north of The Racecourse. This site was excavated extensively in the mid London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

1980s. A preserved antler comb along with human remains and fragments of Neolithic pottery (OA 52B) were recovered from peat deposits at Hoveringham gravel pit, located on the opposite bank of the Thames, directly south-west of The Lake.

3.23. A possible long barrow (OA 132) has been noted as a cropmark feature from aerial photographs around 700 metres to the north-west of The Lake. Neolithic material was also recovered during excavations by OA at Cippenham (OA 167), 1.8km to the north-east of The Lake in the early 1990s. Three unretouched flint flakes (OA 173) were found at Slough Sewage Treatment Works (STW) in 2004, while more worked flints (OA 188) were recovered during work at Manor Farm STW in 1991. A small flint adze was found in the garden of a house at Oakley Green (OA 249) some 150 metre south-west of The Lake in 1963, while a polished axe (OA 278) was recovered from a garden in Dedworth, Windsor around 700 metres to the south-east of the Racecourse. Middle and Late Neolithic pottery and other finds also came from the midden and from tree-holes, plus two Neolithic crouched human burials on the northern edge of the hollow (Allen et al. 2000).

3.24. The Lake

3.25. In Area 6 a shallow hollow ran west-east for 200 m, (OA 13), and contained Early Neolithic middens on a preserved land surface, and tree-holes filled with finds, one of the largest assemblages of finds of this period anywhere in Britain (Allen and Welsh 1997, 1998). As such the site was deemed to be of national importance. Middle and Late Neolithic pottery and other finds also came from the midden and from tree-holes, plus two Neolithic crouched human burials on the northern edge of the hollow (Allen et al. 2000)

3.26. A similar length of the hollow was investigated in Area 10 (OA 14A). Here undisturbed deposits of Early Neolithic material were found at the very bottom of the hollow. The range of material was very large, and included Middle and Late Neolithic finds. A second smaller spread of Early Neolithic struck flint and pottery (OA 15) was found in a patch of preserved soil in Tr. 88 at the very south-east corner of Area 10 (OA 1996, 4.10 and Figure 11). A smaller Early Neolithic settlement was found on the gravel in Area 16 (OA 16). There were also tree-throw holes with Middle Neolithic pottery, and Area 16 also contained two late Neolithic pits. A scatter of tree-throw holes containing Neolithic pottery or struck flint (OA 17A) was also found on Terrace X in excavation Ex1. Middle Neolithic pottery was also found in evaluation trenches H-J (OA 18) and 183 (OA 19) north of Channel S, suggesting a further focus of activity on the gravel terrace here. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

3.27. Beyond the Rowing Course some 200 m to the north is the site of a suspected Neolithic causewayed enclosure (OA 20; Carstairs 1986 Site D; Dyer 1996). Evaluation trenches were dug beyond the north end of the Eton Rowing Course to investigate this, but no clear indication of Neolithic features was found (OA 1991; OA 1995, 3.2.1 and Figure 2). A photogrammetric survey of this site was carried out by RCHME (OA 158). Tree-holes containing Middle Neolithic pottery and struck flint (OA 21) were found along the line of the access road north of the Start End of the Rowing Course (Allen et al. forthcoming). A background scatter of Early and Middle Neolithic pottery and struck flint was also found across Areas 20 and 24, and a Late Neolithic pit (OA 22) was found on Area 24 (Allen and Mitchell 2001).

3.28. At the north-west end of The Lake is a large cropmark ring-ditch (OA 23A), with two or three concentric ditch circuits (Carstairs 1986). A geophysical survey of this was carried out by P Catherall in 2001, confirming the triple ditch circuits.

3.29. Human skulls and other bones were also deposited in the river from the early Neolithic (OA 24 and 25), while a whole Late Neolithic human skeleton (OA 26) dated by radiocarbon to 2880-2580 cal. BC (OxA-8817; 4155 ±45 BP) was recovered from below the water level adjacent to Area 6 (Allen et al. 2000). A Neolithic cattle skeleton (OA 11B) was found in the edge of Channel T in Ex3 (Allen and Welsh 1998). A Neolithic antler and ox skull were found in Area 1 (OA 27), and an Early Neolithic fire with pottery upon it in Area 14 (OA 28). Late Neolithic `burnt mounds’ (dense concentrations of burnt flint and charcoal) and pits full of burnt flint and charcoal were also found in Areas 14 (OA 28) and 16 (OA 29).

3.30. A very large flint scatter (OA 30) was found in Basin R (Allen and Welsh 1996, 1997 and 1998, while one probable hunting camp had a cluster of flint working areas where tools including arrowheads were made, concentrated around a fire (OA 31). Early, Middle and Late Neolithic pottery was also found on the floodplain close to the edge of Terrace X (OA 32). Other concentrations of Neolithic activity were found on the floodplain in Areas 5 (OA 33), Area 3 (OA 34) and Area 6.

3.35. The Bronze Age (2400 BC - 800 BC)

3.36. The Wider Study Area (Figure 4.3)

3.37. A site dating from the Middle Bronze Age (MBA) to the Late Bronze Age (LBA) was excavated at Weir Bank Stud Farm (OA 114/115) 600 metres to the west of The Lake by Wessex Archaeology in the early 1990s. Two concentrations of ring ditches, each identified as cropmarks from aerial photographs are located to the north and north- west of The Lake and the Racecourse. One of these ring ditch groups has been interpreted as a barrow cemetery (OA 223-4) and is located some 300 metres to the north of The Racecourse. The second (OA 232) is located 500 metres to the north- east of The Lake and is overlain by a later Iron Age field system. A single ring ditch (OA 228) has been identified at Boveney Place, around 800 metres to the north-east of The Lake.

3.38. A number of artefact scatters were also identified from this period. A Mid to Late Bronze Age spearhead was found during gravel extraction on Monkey Island Lane (OA 107) around 500 metres to the south-west of The Lake. A hoard of items (OA 108) that included a socketed axehead, a broken knife, a spearhead and a winged axehead was found just over 500 metres to the south-west of The Lake.

3.39. A number of items have been recovered directly from the Thames itself along the boundaries of both the Lake and The Racecourse. Many such finds have been recovered from the river, which appears to have been used a repository for votive offerings throughout prehistory. These finds include two spearheads (OA 130) found in 1909, an Early Bronze Age (EBA) sword (OA 120) found at Headpile Eyot and a spearhead (OA 122) found above , both in 1951. Five LBA swords, a spearhead, dirks, an axe, a knife and a sheath (OA 125) were recovered from near Amerden, Bray. An LBA spear (OA 240) was found at Surley Head Point and another (OA 246) at Oakley court, below Bray, along with a collection of unidentified metalwork (OA 248).

3.40. The Lake

3.41. Cropmarks indicated that there was a group of 4 ring ditches (OA 35) on the gravel terrace at the east end of the site (Carstairs 1986), and these were excavated (Area 6) during the construction of the Rowing Course (Allen and Welsh 1997 and 1998; Allen et al. forthcoming). Three of the ring-ditches were dated. Two to the Early and one to the Middle Bronze. A single ring ditch (OA 36) was also excavated in Area 16 adjacent to Channel T, and was tentatively dated to the Beaker period within the London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

Early Bronze Age. No internal burials were found, but a inhumation of Late Bronze Age date had been dug through the ditch.

3.42. A further ring ditch (OA 37) has been tentatively identified on the gravel terrace north of Channel S. This is a reinterpretation of a cropmark plotted by Carstairs as a D- shaped enclosure (Carstairs 1986), and by the Royal Commission for Historic Monuments () as a penannular ditch (RCHME 1995). The cropmark triple ring ditch at the west end of the site was enlarged at least once during the Bronze Age (OA 23B). Two pits in Area 24 are dated by the struck flints within them to the Early Bronze Age (OA 38).

3.43. On the floodplain in Basin R an Early Bronze Age hearth with pottery (OA 39) was found in Tr. 159 north of Channel T. A concentration of Early Bronze Age pottery, flint scatters and burnt areas in Area EX1 indicated a rare Beaker period occupation site preserved almost in situ (OA 40). Large parts of two Early Bronze Age pots were found close to the channel in Ex2 (OA 41).

3.44. At the edge of Basin W and Terrace X a `burnt mound’ (OA 42) lay at the centre of an extensive scatter of fine charcoal. This was dated to 2290-1970 cal. BC (OxA-10228; 3666 ± 40 BP). Early Bronze Age barbed-and-tanged arrowheads and flint scatters were also found on the floodplain between Terrace X and Area 16, and in Area 4 (OA 43).

3.45. In the Middle Bronze Age (1600-1200 BC) the gravel terrace at the north-west end of the site was divided up by a series of ditched rectilinear enclosures (OA 44). The southernmost enclosure was dug around the triple ring ditch (OA23B). A small group of Middle Bronze Age cremations and a single inhumation were found in the adjacent enclosure. South-east of the main group of Bronze Age enclosures cropmarks and limited excavation indicate that further Bronze Age boundaries (OA 45) ran along the centre of the gravel terrace (Carstairs 1986; OA excavations in 2003).

3.46. Another group of similar cropmark enclosures (OA 46) lies on the gravel terrace north-east of Channel S. Limited evaluation recovered a little Bronze Age pottery from one of the ditches, suggesting that they were also Middle Bronze Age.

3.47. On the gravel terrace south of Channel T there were Bronze Age waterholes, deep and shallow pits and later Bronze Age human and animal burials in Area 10 (OA 14B). A later Bronze Age human burial was dug into the ditch of the Area 16 barrow (OA 36). Small pits full of burnt flint and charcoal (OA17B) were found in Area 11. In Area 6 a scatter of later Bronze Age features including an interrupted ditch, a London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

waterhole, several pits and a gully, was also found around and between the ring ditches (OA 35).

3.48. Channel T continued to be active in the Bronze Age. The channel silts contained both artefactual and waterlogged environmental evidence, including a massive Bronze Age wooden structure (OA 47A) in Area 3, and a smaller jetty (OA 48) in Area 5 (Allen and Welsh 1996; Allen and Welsh 1998). Middle and Late Bronze Age human bones were found on a sandbank in the middle of the channel in Area 1 (OA 49). Middle Bronze Age burnt mounds and pits full of burnt flint and charcoal (OA 36) were found on the channel edge in Area 16, together with human bones. Smaller burnt flint deposits were found in Area 3. A burnt mound (OA 50) was also found running down the gravel terrace edge in Tr. 181 just east of the Mesolithic site (OA 1995, 3.2.4 and Figure 5). Two axes were recovered from Monkey Island a few hundred yards upriver, and one (OA 51A) from close to Queen’s Eyot, the island immediately opposite the Bronze Age enclosures in Areas 20 and 24 (OA 44).

3.53. The Iron Age (800 BC - AD43)

3.54. The Wider Study Area (Figure 4.3)

3.55. Eleven Heritage Assets from this period have been identified within the wider Study Area. An extensive series of cropmarks north of Dorney Reach, some 850 metres to the north-west of The Lake (OA 150), have been plotted from aerial photographs and identified as a series of enclosures, field systems and pit alignments that have been provisionally dated to the later Iron Age. A similarly extensive collection of cropmarks (OA 232) is located around 500 metres to the north-east of The Lake. These cropmarks appear to be mainly the former boundaries of field systems very similar to dated Iron age systems noted across central southern England.

3.56. The excavations at Lake End Road West (OA 179) exposed a settlement site consisting of ditches, enclosures and timber structures that had its origins in the 1st London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

century BC. An excavation carried out by OA on the M4 diversion at revealed part of a trackway and associated timber structures (OA 135) dating from the 1st century BC.

3.57. Some limited evidence for Iron Age settlement was found at Weir Bank Stud Farm (OA 115), 600 metres to the west of The Lake, during the excavations by Wessex Archaeology in 1991. Early Iron Age or Late Bronze Age pottery, a spindle whorl and animal bones (OA 51D) were found in the Hoveringham Gravel Pit on the opposite bank of the Thames to and south-west of, The Lake. Iron Age pottery was also recovered during the excavations at Water Oakley Farm (OA 216), some 190 metres to the west of The Lake, in the late 1950s.

3.58. lA small number of stray finds (OA 253) dated to the Iron Age were recovered close to Water Oakley, Bray. Two iron swords were dredged from the Thames next to The Lake and The Racecourse in the 19th century (OA 124 and 129). The former was in a bronze scabbard and dated to the 1st century BC was found near Armerden in around 1891. The latter was found between Bray Mill and Monkey Island in 1855. An iron axe blade (OA 245) was also recovered close to Oakley Court, Bray.

3.59. The Lake

3.60. An Iron Age settlement at the west edge of Inlet Z (OA 53) was partly uncovered in Area 15 south of the Site (Allen and Welsh 1997), and a further strip of this settlement along the north edge of the widened Return Lane (OA 54) was excavated in 2003 (OA unpublished 2003; Allen et al. Forthcoming). Further Iron Age pits and gullies (OA 14C) were found at the south end of Area 10 (Allen and Welsh 1997). A Middle Iron Age (MIA), enclosure surrounded by a substantial ditch (OA 55A) was created in Area 16 at the north-western corner of the gravel terrace (Allen and Welsh 1998; Allen et al. forthcoming).

3.61. Running diagonally across the MBA enclosure system in Areas 20 and 24 was an Iron Age boundary ditch aligned east - west (OA 56). A ditch at right angles to this ran north from the edge of Channel S, and had a four-post structure (OA 57) alongside it. A sub-rectangular cropmark enclosure (OA 58) was plotted by Carstairs in the north- west corner of the site. There is some doubt as to the date of this feature, although it is certainly prehistoric in origin.

3.62. Five wooden waterlogged structures dating to the Iron Age were found crossing Channel T in Areas 3 (OA 47B) and 5 (OA 59) (Allen and Welsh 1997; Allen and Welsh 1998). These were tentatively interpreted as bridges. In Channel T between areas Ex2 and Ex3 an oak mallet head dated to the LIA, and a LIA scythe, were London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

found (OA 60). In Channel V a large amber bead was recovered from the Late Iron Age or early Roman phase of the channel in Area 4 (OA 61).

3.63. The Paralympic Transport Hub

3.64. The complex of cropmarks noted within the Lake Site (OA 57) and partly excavated in advance of the construction of the northern access road extends north and east into the area of the PTH. This was dated to the Middle or Late Iron Age.

3.65. The Racecourse

3.66. No Heritage Assets from this period have been identified from within the area of the Racecourse.

3.67. The Roman Period (AD43 - 410)

3.68. The Wider Study Area (Figure 4.3)

3.69. Nine Heritage Assets from this period have been identified within the Wider Study area. Evidence for a substantial and high status Romano-British building, that may represent a riverside villa complex have been found at Down Place (OA 181) around 160 metres to the south-west of the Lake. Some limited Romano-British settlement evidence was identified at Weir Bank Stud Farm (OA 115) during the excavations of 1991. The excavations at Lake End Road West (OA 179) revealed an Iron Age settlement site that continued in use into the Roman period.

3.70. Several cropmark features plotted from aerial photographs have been dated to the Romano-British period. A possible trackway and enclosures (OA 117) are visible in a field some 1.2km to the north-west of the Lake, while a further series of enclosures have been identified immediately to the north-west of this site, just to the south-east of River Gardens (OA 118). Cropmarks consisting of hut circles, enclosures, trackways and pits (OA 131) have been identified some 750 metres to the north of The Lake, while a possible hut circle with a diameter of c. 10 metres is visible some 950 metres to the north-east of The Lake.

3.71. Further Roman artefacts were recovered from the excavations at Hoveringham Pit (OA 218), including pottery sherds, jewellery and ceramic building material. Some Romano-British ceramic building material was found during a watching brief at Burnham STW (OA 162). Roman coins along with fragments of weapons and armour are said to have been ploughed up at Easthay (OA 119), some 1.6km to the north- west of the Lake in the late 18th century. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

3.72. The Lake

3.73. Romano-British settlement in the Eton Rowing Course development area was mostly confined to Area 16, where the Iron Age enclosure was first extended and later superseded by Roman ditches (OA 55B). No substantial dwelling house was found within the settlement, although a barn built on post-pads and several corn driers were found, in addition to half a dozen wells and a scatter of deep and shallow pits. A number of infants were buried in the enclosure ditch and other features, and an adult was buried in a coffin within the outer part of the settlement. A long boundary ditch known only as a cropmark ran south-east across the gravel terrace from the south corner of the Roman settlement.

3.74. A small number of pits of early Roman date were found to the east of Area 16 on Area 10 (OA14D). Late Roman ponds containing peat formed in Areas 3 and 5, within which the side of a late Roman cart (OA 62) was preserved (Allen and Welsh 1997). On the south bank of the modern Thames Late Roman skeletons were found at Down Place (OA 63A) (Bates and Stanley unpublished).

3.79. The Anglo-Saxon Period (AD410 - 1066)

3.80. The Wider Study Area (Figure 4.3)

3.81. A late Saxon spearhead (OA 256) was found in the River Thames below the Cut at Bray, some 200 metres to the west of The Lake, in 1951.

3.82. The Lake

3.83. An Anglo-Saxon settlement was found at Down Place cottage south of the modern Thames, overlying late Roman burials (OA 63B). Seven later burials may also be Saxon (Bates and Stanley unpublished). Anglo-Saxon metalwork (OA51B) has been dredged from the modern Thames between Queen’s Eyot and Boveney (Ford 1987, Figure 35). A single Anglo-Saxon inhumation burial (OA 64) was found within Area 6, London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

that of a 7th century woman buried with a collection of amuletic objects at her waist (Allen in Foreman et al. 2002, 28-34 and Figure 3.5). The settlement at Boveney is recorded in the Domesday Survey of 1086, thus indicating a an Anglo-Saxon origin, but little detail is given (VCH 1925). Some elements of the cropmarks recorded south-east and north-east of Boveney (OA 227) may be of Anglo-Saxon origin.

3.88. The Medieval Period (AD1066 - 1485)

3.89. The Wider Study Area (Figure 4.3)

3.90. The remains of five moated sites have been identified within the Wider Study Area. A circular and an L-shaped pond with a central island (OA 101 and 103) located to the east of Fifield House, 1.8km to the south-west of The Lake are thought to be one such site, while another has been recorded at Amerden Bank (OA 128), 100 metres to the west of the Lake. A partially surviving moat is found to the south of Cippenham Court (OA 163), around 1.8km north of the Racecourse Site. A rectangular moat and probable manorial site (OA 257) is recorded at Mills Farm, 1.6km south-west of the Lake, although the ditch itself was in-filled in the mid 20th century course. A quadrangular moat (OA 277) is known at Wolf lane, Dedworth, some 1.2km south of The Racecourse, although this site has since been destroyed by a modern housing development.

3.91. As well as the sites of former manor houses, some remains of the manors themselves along with the ancillary structures from their estates have also survived. The site of the manor at Knight’s Close, Dedworth (OA 274, 275, 276), some 900 metres south of The Racecourse, was excavated in the early 1980s where a substantial hearth and assorted medieval material was recorded.

3.92. Records suggest that West Mill (OA 136) was probably located at Lake End, some 800 metres north-east of the Lake, while the locations of two Fisheries associated London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

with Dorney Manor (OA 210) have been identified along the Thames (OA 221 and OA 244), opposite the Lake site.

3.93. The former Deer Park of Cippenham (OA 170)) that dates back to the mid 13th century was located some 1.7 km north of the Racecourse.

3.94. Two historic village cores dating from the medieval period are located in the wider Study Area, those of Fifield (OA 104) and Dorney (OA 190). Excavations at the convent of St. John The Baptist, Dedworth (OA 280 and 281) exposed the remains of buildings, ditches and pits dating between the 13th and 15th centuries, along with substantial amounts of medieval material.

3.95. Six standing buildings that date from the medieval period have also been identified within the area. These comprise:

• Old Lodge Farmhouse, Bray (OA 105);

• Bell Farmhouse (OA 147);

• Dorney Court, formerly Dorney Manor House, (OA 210);

• The Parish Church of Dorney (OA 213);

• Chapel of St Mary Magdalene, Boveney (OA 283); and

• Parts of a timber-framed house at Dedworth, Windsor (OA 263).

3.96. The Lake

3.97. East of the Rowing Course the hamlet of Boveney is recorded in Domesday, and the church (OA 283; St Marys) is itself of 12th century date (Pevsner and Williamson 1994, 186-7). The remaining Listed Buildings within the Conservation Area (OA 233) are of Post-Medieval origin.

3.98. Cropmarks are evident on aerial photographs south-east and north-east of Boveney (OA 227), and most probably belong to the former late Saxon and medieval settlement, although some may be earlier. One medieval waterhole (OA 66) was found north of Area 6 during construction of the Eton Rowing Course (Allen in Foreman et al. 2002, 85-6).

3.101. The Racecourse

3.102. No Heritage Assets from this period have been identified from within the area of the Racecourse, although it is possible that the mill-stream (OA 282) is of Medieval origin.

3.103. The Medieval Landscape Context

3.104. Both sites lie on the floodplain of the River Thames and outside of centers of dispersed settlement such as that at Boveney. It is likely that both sites were used as meadows in the Medieval period, as well as for arable cultivation. Meadows were highly prized agricultural assets in the Medieval period, providing food for livestock in the winter and early spring, and some grazing. It is recorded that in the winter of 1339-40 the corn crop at Boveney was ruined after heavy rains had flooded the lower lying arable fields (VCH 1925), possibly including those fields indicated by eroded furrows recorded at the Lake site (Area 10; OA14).

The Study Area contains 35 Listed structures (OA 100, 105, 111, 127, 138-142, 147- 149, 151, 153, 159, 177, 178, 190, 209-213, 247, 259-261, 263-4, 267-8, 271-3, 280 and 283) and two historic cores at Dorney and Boveney (OA 190 and 233) that themselves contain 19 and 9 further listed structures respectively. Of the total number of 63 Listed structures, all but 10 are of Post-Medieval origin.

3.108. The two historic core areas are located close to the Lake site with Dorney some 300 metres to the north-west and Boveney bordering the north-eastern edge of the site. Two buildings are located on the opposite bank of the Thames to the Lake (OA 177, Clock Tower and Toad Hall; and OA 247, Oakley Court), otherwise the remainder are scattered across the Study Area between 500 metres and 1.5km from the Lake and the Racecourse.

3.109. The Parish of Bray Tithe Map from 1841 shows that the area to the south of Lake and the Racecourse to be one of open pasture fields with a field pattern almost identical to the current one. No previously unrecorded archaeological or historical features were noted. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

3.110. The Lake

3.111. The villages of Dorney and Boveney were both recorded in Domesday as separate manors (Munby in Foreman et al. 2002, 18). Historic maps show that the Lake site has been part of Dorney field since the 18th century, and it is likely that Dorney field was part of the medieval three-field system prior to that (Munby in Foreman et al. 2002, 19-21). Medieval and post-medieval remains, which consist of field ditches and furrows from ridge-and-furrow cultivation, are known from cropmarks running east- north-east in the north-west of the site, and were excavated in Area 24 (Foreman et al 2002. Fig. 1.4). Further furrows, running north-west, were found across Area 10 (OA14). Post-medieval ditches were also found crossing Area 6 (Allen and Welsh 1997), while a group of postholes were revealed in evaluation just to the north (OA 1991). A curving post-medieval ditch ran across Area 20 just west of Channel S.

3.112. Historic maps show that by the 17th century Dorney Field had been subdivided into a patchwork of small fields (Rocque 1761). By the early 19th century some of these had been amalgamated into four principal strip at right angles to the Thames (Boveney estate map 1812). By the later 19th century (1st edn Ordnance Survey 25” map, 1875), this amalgamation had reduced this to three, and by 1899 to only two principal fields (OS 2nd edn 25” map). This situation persisted throughout the first half of the 20th century, although cropping divisions within the largest field were plotted on the OS 4th edn (1932). By 1972 the last boundary had gone, though its position was still marked by a few large trees (OS 1972).

3.113. The Paralympic Transport Hub

3.114. No Heritage Assets from these periods have been identified from within the area of the PTH.

3.115. The Racecourse

3.116. No Heritage Assets from this period have been identified from within the area of the Racecourse, although the mill-stream (OA 282) may be regarded as a historic landscape feature.

3.117. Fewer historic maps are available for the Racecourse site but the limited surviving evidence indicates that the site was probably used as meadows and/or pasture and was known in the early 19th century as ‘The Rays’ (VCH 1923) . A water-mill was located along the mill-stream, just to the north of the present Clewer village.

3.119. The Wider Study Area (Figure 4.3)

3.120. The Study Area contains 35 Listed structures (OA 100, 105, 111, 127, 138-142, 147- 149, 151, 153, 159, 177, 178, 190, 209-213, 247, 259-261, 263-4, 267-8, 271-3, 280 and 283) and two historic cores at Dorney and Boveney (OA 190 and 233) that themselves contain 19 and 9 further listed structures respectively. Of the total number of 63 Listed structures, all but 10 are of Post-Medieval origin.

3.121. Six standing Listed Buildings that date from the medieval period have been identified within the Study Area. These comprise:

• Old Lodge Farmhouse, Bray (OA 105, Grade II);

• Bell Farmhouse (OA 147 -Grade II*);

• Dorney Court, formerly Dorney Manor House, (OA 210, Grade I);

• The Parish Church of Dorney (OA 213, Grade I); and

• Parts of a timber-framed house at Dedworth, Windsor (OA 263, Grade II); and

• The redundant Chapel of St Mary Magdalene, Boveney (OA 283, Grade I) (discussed below in relation to the Lake site).

3.122. In addition to the Listed Buildings noted above, there are 3 structures, 2 of which are recorded in the HER as of some historic interest (OA 126 and OA 265). These comprise:

• A water-mill on the Thames (OA 126);

• A barn known as ‘Tudor Barn’ (OA 265); and

• The Royal Windsor Pavilion at Windsor Racecourse within the Racecourse site (OA 284).

3.123. The Lake and PTH

3.124. The hamlet of Boveney, to the east of the Lake site, is recorded in Domesday, and the chapel (OA 283; St Marys) is of 12th century date (Pevsner and Williamson 1994, 186-7). The Listed Buildings within the Conservation Area (OA 233) are of Post- Medieval origin. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

3.125. The redundant chapel of St Mary Magdalene (OA 283) located to the east of the village core, has a 12th century core but with significant rebuilding dating primarily to the 15th and 16th centuries.

3.126. Most of the Listed structures noted above will be screened to varying degrees from the site by the existing trees and hedgerows around the edge of Boveney. It is possible that part of the eastern end of the proposed temporary pedestrian river crossing (TPRC) will be visible from the chapel of St Mary Magdalene (OA 283) and vice versa.

3.127. The Racecourse

3.128. The Royal Windsor Grandstand was built in the late 19th century at the east end of the course and still retains many original Victorian features (OA 284; http://www.windsorraces). It is shown as part of a small complex of structures on the Ordnance Survey First Edition map of 1871. It is possible that other, smaller structures and facilities of 19th and early 20th century origin survive within the Racecourse site but no systematic survey or recording appears to have been undertaken to date. Any such structures are most likely to survive in the area around the Grandstand.

3.129. The Historic Landscape

3.130. The Wider Study Area (Figure 4.3)

3.131. No Designated historic landscape assets have been identified in the wider Study Area.

3.132. The Lake and PTH

3.133. No Designated historic landscape assets have been identified within or bounding the Lake site

3.134. The hedgerow defining part of the southern perimeter of the PTH may meet the criteria to be termed an ‘Important Hedgerow’ according to the provisions of the 1997 Hedgerow Regulations (OA 286).

3.135. The Bucks HER Historic Landscape Characterisation (HLC) programme has recorded the surrounding landscape in which the lake site sits as a patchwork of fields enclosed at varying dates. The river-bank where the west end of the TPRC would be located is recorded as former parkland. The Lake site itself retains little of its former historic landscape character. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

3.136. The Racecourse

3.137. No Designated historic landscape assets have been identified within or bounding the Racecourse site. The mill-stream (OA 282) may be regarded as a historic landscape feature, however it now lies in a landscape context far removed from its origins.

3.138. The hedgerow defining the northern boundary of the Balloon Meadow may meet the criteria to be termed an ‘Important Hedgerow’ according to the provisions of the 1997 Hedgerow Regulations (OA 285).

3.139. No HLC data is available for the area of Berkshire in which the Racecourse is located, however the site retains little of its pre-racecourse historic landscape character. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

4.0 Archaeological Potential and Survival

4.1. Previous Impacts and Survival

4.2. Previous impacts within the Lake site, ie ground disturbances that have affected the survival of below-ground archaeological deposits, have been considerable, and are shown on Figure 4.5. The construction of the Eton Rowing Course and Return Lane has removed all archaeological deposits within their footprints, and grading of the sides of both watercourses has also removed or truncated any archaeological features immediately alongside. The effects of the grading were largely dealt with by archaeological excavation and watching brief during the construction.

4.3. Construction of the Rowing Course and Return Lane also involved the excavation of large parts of the Site as borrow pits south-west of the Return Lane. Following archaeological investigation, these have removed nearly half of the area of the Lake site.

4.4. It was also necessary to divert a major gas main that crossed the Rowing Course towards the Finish End, and the area dug out for this is also shown (between Area 15 and Area 4) on Figure 4.5. The previous course of the gas main south-west of this had also destroyed a narrower corridor some 10 m wide.

4.5. The construction of the Boathouse and of the Finish Tower have also removed any archaeological deposits within their footprints.

4.6. The archaeological investigation in Area 6 involved the complete excavation of the ring ditches and the hollow, so within the excavation area there is no surviving potential.

4.7. The area of the river-bank where the TPRC will be sited and the pasture fields of the PTH have not been subject to detailed archaeological examination as part of the planning process. Consequently, the extent of any previous impacts at these locations have not been identified in detail as for the bulk of the site to the west.

4.8. As previously discussed, the underlying geology has a significant effect upon the type of archaeology likely to be encountered, and the depth at which it occurs.

4.9. It is less certain what form and extent previous impacts may have taken on the Racecourse site. Reference to historic mapping, aerial photography, and ground London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

observation suggests that this land was used as meadow and pasture through the Medieval period and well into the Post-Medieval period. These are forms of land-use that are unlikely to have resulted in any other than localised and relatively minor impacts (eg livestock poaching).

4.10. The development of the Racecourse as a sporting venue in the latter part of the 20th century may have resulted in the following potential previous impacts:

• landscaping of the course itself, including ground-levelling and the planting of trees;

• the insertion of services to the various facilities including drainage of the racecourse and parking areas;

• the construction of the paths, tracks and access roads;

• landscaping of the parking areas;

• the construction of the various buildings at the east end of the site; and;

• maintenance of the river-bank and of the wooded areas.

4.11. Archaeological Potential

4.12. The Rowing Lake site and PTH has a high potential to contain significant archaeological deposits dating from the Mesolithic to Anglo-Saxon periods. However, the construction of the current facilities and the preceding archaeological interventions on the site will have resulted in the partial or complete removal of many of these deposits. Most of the length of the access road lies over ground that is archaeologically ‘sterile’ but the road does cross part of the preserved area west of the Neolithic and Bronze Age features recorded within a possible Middle Bronze Age enclosure (OA 23 A and B, Figures 4.4 and 4.5). It is uncertain exactly what the extent is of this preserved area at the time of writing as it is understood by OA that this preserved area may not necessarily have been respected. The PTH overlies a complex of cropmarks (OA 57) which have been shown in previous excavations further to the south and west to be of Iron Age date.

4.13. The apparent paucity of archaeological sites and finds from the Racecourse site reflects the low level of archaeological interventions rather than a low archaeological potential. Given the density of significant archaeological deposits recorded from the Rowing Lake site, which sits in a similar riverside location in the local landscape, it is London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

very likely that the Racecourse site also contains significant but currently unrecorded archaeological deposits.

4.14. It is difficult to predict the archaeological potential of the river itself but it should be noted that rivers adjacent to settlements (or in proximity to fords or bridges) often contain deliberately placed items such as metalwork of the Later Prehistoric, Roman and Anglo-Saxon periods. In addition, the previous channels (palaeochannels) of the River Thames are known to lie distributed across the flood-plain and what is now the river may have been a habitable or useful location in, for example, the Bronze Age or Iron Age. The present course of the River Thames adjacent to the sites is likely to have become increasingly stabilised from the Medieval period onwards.

5.0 Potential impacts and Mitigation

5.1. Overview of the proposals

5.2. This assessment of these proposals was informed by the suite of drawings issued by LOCOG numbered POP-A-O-RO-XX, SBH-ATK-ZZ-ETD-DR-C-1-E5-0004, 785002- ETD-02 and 2216001-14ETD-106, 22216001 - 14ETD-404, 0241-ETD-FBR-T-DGA- 0001 - 17, the Stage C Concept Design Report (Atkins Global) and by conversations with representatives of London 2012 and their consultant team and contacts from Eton College: Andrew Boyd (Associate, Savills); Ivor Lloyd, (Managing Director of the Eton Dorney Rowing Lake); Henry Westwood (Atkins Global); and David Banks (London 2012).

5.3. The proposals are set out in some detail in the supporting Design and Access Statement. In summary the proposals for the Dorney Lake site comprise:

• Operational compounds and athlete areas at the southern end of the lake, consisting of tentage and portacabin-type structures;

• Athlete facilities, secondary broadcast compound and storage at the north end of the lake, as above;

• Spectator seating and associated event facilities (eg ticket facilities, concessions and medical facilities) on the eastern side and the southern end of the lake;

• Ancillary spectator facilities to the east of the stands and lake including the construction of the paths, tracks and access roads;

• Grandstand seating for 2,000 FISA Family spectators and 1,500 for accredited groups will be located on the return island near the finish line;

• The Paralympic Transport Hub;

• Perimeter security fencing; and

• A broadcast compound will also be located on the western side of Dorney Lake with a cable route running beneath the return lake to the return island.

5.4. In summary the proposals for the Windsor Racecourse site comprise: London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

• Temporary blue badge car parking, coach, taxi and motorcycle parking areas using both the existing parking facilities and grassed areas laid with trackway;

• Staff facilities comprising tentage and portacabin-type structures;

• The construction of temporary paths, tracks and access roads; and

• Pedestrian Screening Area (PSA) including ticket, toilet and other visitor facilities.

5.5. Access between the Lake and Racecourse sites will be via the TPRC , an ten metre wide bridge with sufficient clearance for boats to pass under. The bridge will have a span of 45m and is likely to be a steel structure of a similar design to that used for the Reading Festival. The bridge will be partly supported by piles driven into the river- bed. Concrete or hardcore footings are also likely to be built on each bank to accommodate a mobile platform lift. These may be up to c 800mm deep. A number of trees will be removed on each bank but it is anticipated that this will not result in any below-ground disturbance.

5.6. It is anticipated that none of the facilities noted above will be of a permanent nature and will comprise temporary tents, pavilions, portacabin-type structures, scaffolding- based stands, portaloos etc. All services will run over-ground and no services will be buried, including the broadcast cabling. Where some new footpaths and tracks are installed, then these will be on plastic or metal interlocking plates. The main broadcast compound will be located within the previously stripped and re-instated area and will not be dug deeper than any previous disturbance.

5.7. It is possible that minor and very localised impacts may occur where pegs and/or posts are used to secure tents, pavilions, perimeter security fencing and part of the spectator stands.

5.8. Part of the southern access road to the Lake will be broadened and laid with gravel. This will comprise a narrow margin adjacent to the existing road.

5.9. Walkover Survey

5.10. Introduction

5.11. Windsor Racecourse and the Eton College Rowing Centre were both visited on the morning of Friday July 16th 2010. The weather was mixed, with sunshine and showers, some quite severe. This did not restrict access to any part of the sites.

5.12. The Racecourse London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

5.13. The vast majority of the areas designated for temporary parking and camping are currently under grass. It is very even and appears to have been landscaped. Some raised banks have been created around the perimeter. The parking area within the racetrack itself is more uneven, with long linear earthworks, but the cause of these is not apparent.

5.14. The main exception to this landscape character is the proposed motorcycle parking area which is currently covered with gravel.

5.15. The proposed new access routes to Balloon Meadow on the south side of the racecourse involve creation of breaks in the existing hedgerow (OA 285). The hedge and trees along the western side appear ‘natural’ rather than the obviously planted hedges to the east and south of this area.

5.16. The temporary river crossing and PSA will be located at the far western side of the Racecourse. While this area has been less well maintained than other parts of the course, with patches of rough ground and evidence for dumping, the majority is part of the landscaped grassed area. The boundary of the site along the bank of the river has retained its natural vegetation, scrub and large trees. There are some breaks in the trees, one of which should match the location of the bridge. The river-bank shows no evidence for man-made landing stages or revetments.

5.17. The Lake Site and Paralympic Transport Hub

5.18. The riverbank east of the boathouse has a concrete landing stage. The path continues eastward along a stretch of natural riverbank with trees before reaching another revetted stretch of moorings. The east end of the TPRC will be located here, in a gap in the treeline.

5.19. The area around the existing Eton College Rowing Centre building at the east end of the complex is already used extensively for movement of boats and areas where large numbers of people congregate and includes extensive areas of roadway and hard surfacing, with an existing surfaced parking area. The remainder of the area is under landscaped grass.

5.20. The fields for the proposed PTH are currently in pasture.

5.21. There is more tree cover within the grassed area to the north-east of the existing car park, already used as overflow parking, where plans suggest some clearance may be required. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

5.22. This area proposed for the broadcasting compound is currently under grass, which will be stripped and the topsoil removed. It was confirmed that this had been the site of the construction compound for recent work on the return lane and bridges. As part of this process the topsoil had been removed, a temporary gravel surface laid, and the area then reinstated.

5.23. The vast majority of the areas across the venue where temporary facilities will be placed lie within areas of previous disturbance and landscaping. The TPRC will affect stretches on and around the riverbank on both sides of the Thames where there has been no previous development.

5.24. Archaeological Assets - Potential Impacts

5.25. Given the minimal and localised potential impacts noted above, it is generally anticipated that the proposals will not result in significant impacts to archaeological assets. There are two possible exceptions to this: the TPRC, which is likely to include piles on the river-bed and two areas of footings, one on each bank; and the possible broadening of the southern access road.

5.26. The depth of the possible excavation for the TPRC footings is likely to be c 800mm deep and will cut through the topsoil and into the underlying gravel or alluvium. No information on the depth of piling is available at the time of writing.

5.27. Any archaeological deposits within the soils and gravel or alluvium excavated for the footings will be removed or truncated. Any archaeological deposits (including artefacts and ecofacts) within the footprint of the proposed piles will be removed or truncated. Further, localised impacts may occur during removal of the bridge.

5.28. Part of the southern access road to the Lake will be broadened and laid with gravel. This will comprise a narrow margin adjacent to the existing road. Most of the length of the access road lies over ground that is archaeologically ‘sterile’ but the road does cross part of the preserved area west of the Neolithic and Bronze Age features recorded within a possible Middle Bronze Age enclosure (OA 23 A and B).

5.29. Built Heritage Assets - Potential Impacts

5.30. It is anticipated that the proposals will not result in any permanent changes to the fabric or setting of any built heritage assets. It is possible that temporary impacts (ie operational impacts) may occur to the settings of some built heritage assets (eg the Boveney Conservation Area, OA 233 or the Grade I Listed chapel of St Mary Magdalene, OA 283) deriving from changes to the landscape, and changes in noise, London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

traffic and light. However, with the exception of the TPRC , such temporary impacts already occur during busy periods of use of both of the Lake and the Racecourse, and therefore these impacts may not be regarded as significant.

5.31. Historic Landscape Assets - Potential Impacts

5.32. It is anticipated that the proposals will not result in any permanent changes to the fabric or setting of any historic landscape assets.

5.33. It is possible that temporary (ie operational impacts) may occur to the perception of the local environment from public rights of way deriving (eg footpaths around Dorney or the River Thames towpath) from changes to the landscape, and changes in noise, traffic and light.

5.34. The River Thames towpath is partly screened from the Lake site by the tree-line along the river-bank but the TPRC will be in plain view from the tow-path, which will pass underneath the bridge.

5.35. Mitigation Options

5.36. It seems unlikely that any practical mitigation measures could be devised that would address the predicted minor and temporary changes in setting to the built heritage and the historic landscape.

5.37. It is likely that the archaeological advisors to the local planning authorities concerned would require some form of mitigation to be devised to counter the potential impacts of the proposals on the archaeological resource. This applies in particular to the proposed footings and piling of the TPRC across the Thames, and the widening of the access road which have been identified here as the only two elements of the proposals that may have a significant impact on any archaeological deposits present. OA will enter into discussion with the archaeological advisors to each of the local authorities concerned to formulate an investigation and management strategy. It is unlikely that any realistic and practical mitigation measure could be applied in advance or during insertion of the piling but it is easier to mitigate any potential impacts from the footings on the river-bank or the access road widening. This could be achieved by either a pre-construction archaeological field evaluation of the proposed impacted areas or by means of an archaeological watching-brief during the earthworks phase of construction. It would also be possible to maintain a more general archaeological watching-brief during the construction phase of the project London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

upon any new, unidentified activities that may result in impacts to any archaeological deposits present. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

6.0 Conclusion

6.1. There are no Cultural Heritage Designated Sites within the either the Lake or Racecourse sites. The nearest Designated assets are a cluster of Grade II Listed Buildings in the core of the historic village of Boveney (within a Conservation Area) immediately to the north of the Lake site, and a Grade I Listed Building (a redundant Medieval chapel) located to the east of the Lake site.

6.2. The extensive recorded assets principally derived from various archaeological interventions on the Lake site that were undertaken in advance of the construction of the current facilities. The construction of the current facilities will thus have, in many cases, removed much if not all of the archaeological deposits from which these discoveries were made. The areas where the TPRC and the PTH will be sited have not been subject to detailed archaeological examination as part of the planning process. Consequently, the extent of any previous impacts at these locations have not been identified in detail as for the bulk of the site to the west.

6.3. The Rowing Lake site and PTH has a high potential to contain significant archaeological deposits dating from the Mesolithic to Anglo-Saxon periods. The apparent paucity of archaeological sites and finds from the Racecourse site reflects the low level of archaeological interventions rather than a low archaeological potential. It is very likely that the Racecourse site also contains significant but currently unrecorded archaeological deposits.

6.4. It is difficult to predict the archaeological potential of the river itself but it should be noted that rivers adjacent to settlements (or in proximity to fords or bridges) often contain deliberately placed items of the Later Prehistoric, Roman and Anglo-Saxon periods.

6.5. One hedgerow has been identified within the Racecourse site and another defining part of the PTH that may meet the criteria to be termed Important Hedgerows, according to the provisions of the Hedgerow Regulations of 1997.

6.6. It is anticipated that the proposals will not generally result in significant impacts to archaeological assets. There are two possible exceptions to this: the TPRC, which is likely to include piles on the river-bed and two areas of footings, one on each bank; and the possible broadening of the southern access road. London 2012 Olympic Rowing, Canoe Sprint and Paralympic Rowing events September 2010

6.7. Any archaeological deposits within the soils, gravel or alluvium excavated for the footings or the access road widening will be removed or truncated. Any archaeological deposits within the footprint of the proposed piles will be removed or truncated. Possible mitigation measures include pre-construction archaeological field evaluation or an archaeological watching-brief.

6.8. It is anticipated that the proposals will not result in any permanent changes to the fabric or setting of any built heritage assets and elements of the historic landscape. It is possible that temporary impacts may occur to the settings of some heritage assets deriving from temporary changes to the landscape, and temporary changes in noise, traffic and light. However, such temporary impacts already occur during busy periods of use of both of the Lake and the Racecourse, and these impacts may not therefore be regarded as significant.

Project funded by Summerleaze. 115 Archaeological Weir Bank Stud Farm. This site was first identified from cropmark evidence showing enclosures and HER(BERKS):MRW13 site ditches. A series of archaeological investigations between 1989-1991 in advance of gravel extraction 2 identified five phases of activity, particularly a small Middle Bronze Age settlement. The five phases of 1232931 human activity identified at the site were: Mesolithic flint assemblage indicative of single or repeated use of the area. Earlier Neolithic: small-scale activity, pottery sherds and two features identified. Later Neolithic/early Bronze Age: artefactual evidence, mainly pottery. Middle Bronze Age: the major phase on the site, excavated features include field ditches, roundhouses, pits and hollows, representing a field system and a later small rural settlement. Late Iron Age/early Roman: small-scale activity, mainly artefactual evidence i.e. pottery sherds, from three small features. The site was completely destroyed by the excavation and subsequent gravel extraction. A possible Prehistoric or Roman trackway is also visible here as cropmarks on aerial photographs. It is defined by parallel ditches measuring 70m long. The trackway has been recut at some stage and another set of parallel ditches is visible parallel to the original ditches. 116 Archaeological Low density pottery scatters found by Thames Valley Archaeological Services during watching brief for NMR:1084277 site Mid Southern Water Company plc in 1989. 117 Cropmarks A possible Prehistoric or Roman trackway and enclosures are visible as cropmarks on aerial NMR:1232930 photographs.
