CPAT Report No 1598 Dyserth Water Treatment Works Archaeological Assessment

Summary In June 2018 the Clwyd Powys Archaeological Trust (CPAT) carried out an archaeological assessment on behalf of Caulmert in connection with an extension to the current water treatment works at Dyserth in Denbighshire. The proposed site is located immediately to the west of the existing treatment works and is currently pasture. There is fragmentary evidence for occupation of the wider area during the Neolithic and Bronze Age and known occupation of sites at Meliden during the Roman period and Dyserth during the medieval period. However the archaeological potential of the site, based on the pattern of known occupation of area has been assessed as low. A geophysical survey carried out in 2018 revealed a number of anomalies within the proposed Development Area. No features were identified that signified notable archaeological potential.

CPAT Report No 1598 Dyserth Water Treatment Works, Denbighshire Archaeological Assessment

1 Introduction 1.1. The Clwyd-Powys Archaeological Trust was engaged by Caulmert Ltd to carry out an archaeological assessment on the site of a proposed extension to the Dyserth Water Treatment Works in Denbighshire (NGR SJ 0517 7968). The existing treatment works lies to the north-west of the village, alongside the A547 road, with the proposed extension situated immediately to its west and covering an area of approximately 0.5ha. The work was subject to a Written Scheme of Investigation (CPAT WSI 1938), which was approved by Mark Walters, the Archaeological advisor to Denbighshire Council, acting in his role as the archaeological curator for the region.

1.2. The assessment comprised an initial desk-based study of readily available sources to identify the archaeological resource of the Development Area and its environs, followed by a geophysical survey to determine whether there was any evidence of sub-surface archaeological features, in as far as these could be identified.

1.3. The geophysical survey was carried out in June 2018 and the evidence was combined with the desk-top study to produce this report immediately thereafter.

CPAT Report No 1598 Dyserth Water Treatment Works, Denbighshire Archaeological Assessment

2 Archaeological Background 2.1. There is little evidence of prehistoric activity within 500m of the proposed development. A stone axe made at Graig Lwyd was found in a garden at Dyserth in 1982, but no evidence for associated settlement has yet been identified.

2.2. Again, evidence of Roman activity in the immediate area is sparse, the only record relating to a trackway that served Bodrhyddan Hall and which has been suggested to follow the line of a Roman road. That said, the Roman industrial complex at Melyd Avenue, Prestatyn, lies only 2.3km to the north-north-east and clearly indicates a sizable Roman presence, probably associated with the mineral deposits found on Graig Fawr and the other limestone hills in the vicinity.

2.3. The Development Area falls within the township of Llewerllyd, which appears in the Domesday survey of 1086 as part of the town of Rhuddlan but is now part of Dyserth. It was recorded as one of the holdings of Earl Edwin in 1066, but by the time of the survey it was held by Earl Hugh of Chester and Robert of Rhuddlan. It was associated with three ploughlands and two fisheries, but these have not been located.

2.4. Land within the township is referred to in documents held by the National Library of Wales and dating from the 16th century, though it is not possible to identify the Development Area in any of these. The earliest map coverage of the area dates to 1810 and is held by the National Library of Wales, but contains no useful information regarding the Development Area.

2.5. It is informative that the 1839 Tithe map and apportionment name the field (No 345) in which the development is proposed as ‘Maes y Saes’, the ‘maes’ element of the name implying that this was, or had once been, an open arable field of probable medieval origin. The ‘saes’ element identifies an English, or perhaps more particularly Saxon, background and it is likely that this comes from the field being within the control of the settlement at Rhuddlan. A number of groups of ‘maes’ field names exist in the surrounding area and it seems likely that these were once combined to form the areas of open field referred to as ploughlands, above.

2.6. The later mapping of the locality by the Ordnance Survey for the late 19th-century 1:2500 maps reveals no more than that the southern part of the Development Area was crossed by a footpath which linked Dyserth with Llewerllyd Farm. No heritage assets are identified here on any of the Ordnance Survey mapping from 1872 to 1938.

3 Desk-based Assessment 3.1. As far as could be determined from the search of readily available sources, no heritage assets either designated or undesignated are located within the proposed Development Area itself.

HER records Designated Assets 3.2. There are four designated assets within 500m of the Development Area. Located 240m to the north-west is Llewerllyd (LB1493) a Grade II listed 17th century farmhouse rebuilt in red brick in 1783. Located 300m to the east is Dyserth Hall (LB1360) a Grade II* listed 16th century gentry house built in limestone and extended in separate phases during the 18th century with conjoined rear wings. A Grade II listed stone built roadside well (LB25957) is located on the modern A547 to the east of Dyserth Hall. The well has been attributed to the hall complex and tentatively dated to the 16th or 17th century.

3.3. Located 440m to the south of the Development Area is the northern boundary of Bodrhyddan Hall park (C54, Fig. 5 outlined in blue) a Registered Parks and Gardens associated with Bodrhyddan Hall itself, a Grade I listed 17th century country house located 1.1km to the south-west.

Undesignated Assets 3.4. 20 undesignated assets were located within 500m of the Development Area. Most of these assets were of little or no relevance in assessing the archaeological potential of the Development Area.

CPAT Report No 1598 Dyserth Water Treatment Works, Denbighshire Archaeological Assessment

3.5. A post-medieval trackway (PRN93605) runs north-east from Bodrhyddan Hall, approximately 70m to the south-east of the Development Area. This has been suggested as the route of a Roman road linking the settlement in and around Meliden and Prestatyn with the putative Roman fort at Varis near St Asaph. The route of this road is believed to have passed close to Dyserth, underlying the extant trackway. The existence of such a road has, however, still to be confirmed (Jones et al, 2015 p.9). A recent evaluation on land adjacent to the track provided no evidence to support the assertion that the track might follow the line of a Roman road however (Grant, 2018, p.13).

3.6. Artefacts recorded within 500m of the development are predominantly medieval and post medieval in date and located within an area within the medieval core of Dyserth, 390m to the south-east of the Development Area. A stone axe (PRN103093) believed to be Neolithic in date was recovered from a residual context in Dyserth 400m south- east from the Development Area.

3.7. A Bronze Age palstave axe and Roman artefacts including two coin hoards and a number of isolated finds have also been recorded within Dyserth further to the south, indicating that there has been a long period of continuous occupation of the area.

4 Geophysical Survey Report 4.1. The Geophysical survey and LiDAR analysis was carried out by Chris Matthews of Archaeological Surveys West (ASW) on behalf of CPAT. The following section is reproduced from the report dated June 2018.

LiDAR analysis 4.2. The LiDAR data for this site was sourced from Natural Resources Wales (lle.gov.wales) and processed using QGIS. The data consists of a 1m resolution Digital Terrain Model (DTM) which was used to produce the Hillshade plots. The features observed within the survey area consist of the following (Fig. 7):

A- This feature consisted of a weak positive linear (built up) running parallel to the south-western boundary. It is likely to be the result of ploughing or a track-way.

B- This feature consists of regular weak linears running north-east to south-west through the field and is likely the result of ploughing.

C- This feature consists of a strong negative linear (ditch) running north-east to south-west through the field and is likely the result of crop separation or an earlier field boundary.

D- These feature consists of several weak linears running south-east to north-west from the southern boundary and are likely the result of ploughing.

E- This feature consists of a weak linear bank running parallel with the eastern field boundary and is likely to be a track.

Magnetometry 4.3. The purpose of geophysical survey is to identify the archaeological potential of an area of land in a non-intrusive, quick and relatively inexpensive way. To achieve all three and still produce the highest standard of data possible that also identifies the widest range of past human activity, the survey method of magnetometry was chosen.

4.4. Magnetometry measures and maps the background magnetic field and any local anomalies. These anomalies can be caused by the presence of features containing greater or lesser magnetic properties than the soils around them. This can be due to the natural magnetic properties of the feature, as well as, a range of taphonomic processes that alter its magnetic properties. As a broad example, buried walls and built-up features, such as banks, appear as negative magnetic anomalies, where as a ditch would appear as a positive anomaly. These can be distinguished from responses caused by ferrous materials and areas of intense burning (thermoremanence), based on the strength of the magnetic response.

4.5. The equipment used for the survey was a dual sensor Bartington Instruments Grad 601-2 fluxgate gradiometer. This instrument consists of two sets of sensors, each mounted with a vertical separation of 1m, one set at each end of a 1m long horizontal bar. This provides two sets of parallel readings and, under normal operating conditions, is capable of surveying to a depth of between 0.5m to 1m.

4.6. To set out the survey grids, a Trimble R4 GPS run with a VRS correction was used, with an accuracy of 0.014m. The survey area was plotted with a temporary grid of 20mx20m using coordinates set out in QGIS. Each 20mx20m grid was then walked using a zig-zag traverse with a sample interval of 0.25m (4 points per meter) and traverse interval of 1m.

4.7. Prior to commencement of the survey the field had been cut and weather conditions were dry. The only observable obstruction or disturbance within the survey area was a plastic and metal pipe set into concrete, likely related to geological testing. Across the survey area were a number of metallic spikes, these are usually attributed to surface objects or metallics within the topsoil. The analysis of features are as follows (Fig. 8):

F1- This feature consists of strong positive linear anomaly with low gradient edges running across the north-west boundary. The greater magnetic properties of this feature and its form indicate a probable cut feature such as ditch or former boundary.

F2- This feature consists of a small circular isolated anomaly with a stronger positive reading than the surrounding soils and low gradient edge, indicating the presence of fired material (i.e. brick) or a cut feature such as a pit.

F3- This feature consists of regular weak linear striations visible throughout the survey area, running from north-east to south-west. These anomalies indicate ploughing activity following the same direction as plough features visible in the LiDAR data (Fig. 7).

CPAT Report No 1598 Dyserth Water Treatment Works, Denbighshire Archaeological Assessment

F4- This feature consist of a small irregular shaped and isolated anomaly with a stronger positive reading than the surrounding soils, indicating the presence of fired material (i.e. brick) or a cut feature such as a pit.

F5- This feature is the result of a modern magnetic disturbance generated by the south- eastern field boundary and adjacent road.

F6- This feature consisted of a linear strong negative anomaly which is likely to be the result of modern disturbance caused by the waterworks fence boundary and the road to the south.

F7- This feature consist of a strong positive disturbance with low gradient edges adjoining the eastern field boundary. The feature is likely to be the result of modern disturbance caused by the waterworks fence boundary but could also could indicate a deposit of fired material or an event of burning.

F8- This feature consists of a positive linear and area of slightly lesser magnetic readings running from north-east to south-west through the centre of the survey area. The readings suggest a built up feature flanked by ditches indicating a track or boundary. The feature appears to correspond with a strong linear observed in the LiDAR Hillshade analysis (Fig. 7).

F9- This feature is the result of a modern magnetic disturbance generated by the metallic wire mesh field boundary adjoining the waterworks which is visible across the eastern extent of the survey as well as a large metallic spike that was the result of a plastic and metallic pipe set into concrete.

F10- This feature consist of a small circular anomaly adjacent to a large linear feature (F1) and consists of a strong positive reading with a low gradient edge, indicating the presence of fired material (i.e. brick) or a cut feature such as a pit.

5 Conclusion 5.1. The proposed site is located immediately to the west of the existing treatment works and is currently pasture.

5.2. The HER search identified fragmentary evidence for occupation of the wider area during the Neolithic and Bronze Age, based on isolated finds within the town of Dyserth 0.4km to the south-east of the site.

5.3. There was occupation at a site near Meliden to the north-east during the Roman period. However no evidence for occupation within the immediate vicinity of the Development Area has been identified. The pattern of finds recovery in the immediate area, including two coin hoards and a quern indicate that there may have been occupation of a site at or near Dyserth.

5.4. The provenance of a hypothetical Roman road running to the south-east of the Development Area is unclear, especially as the terminus of the road to the south-west believed to be at or near St Asaph has yet to be determined.

5.5. Dyserth was formed during the medieval period and a number medieval and post medieval finds have been recorded in the town and the immediate vicinity. However there is no evidence for occupation of the Development Area during the period. The 1839 Tithe Apportionment records the site under the name ‘Maes y Saes’ indicating an arable field, under English ownership. This was one of several fields with a similar name in the vicinity of the Development Area, which are likely to have formed part of the medieval holdings of the settlement of Rhuddlan, 4km to the south-west.

5.6. This geophysical survey produced evidence of agricultural activity within the field that appeared to follow the same orientation as the modern field, as well as, linear features visible in the LiDAR analysis. A possible former boundary or track was visible on both the LiDAR and magnetic data but also appeared to follow the same alignment as the modern field and plough scars. This indicated that the features were likely to be modern in date. A linear feature was also identified running parallel with the stream to the north and was likely to be an earlier boundary or channel connected to the stream which appeared to have been canalised around the waterworks (Matthews, 2018, 8).

5.7. Background disturbances generated by the metallic fence on the eastern boundary, and a road to the south did limit the clarity of this survey. However, based on the areas unaffected by modern disturbance, no features have been identified that signify notable archaeological potential (ibid, 8-9).

1 Introduction 1.1. The Clwyd Powys Archaeological Trust (CPAT) has been requested by Caulmert Ltd to submit a proposal for an archaeological assessment in connection with an extension to the current water treatment works at Dyserth in Denbighshire. The area comprises approximately 0.5ha of land which is currently pasture and is centred at NGR SJ 0517 7968, to the west of the existing works.

1.2. The regional Historic Environment Record (HER) does not appear to contain any evidence of heritage assets in the immediate area of the proposal, but some recent work nearby has suggested that there is a possibility that sub-surface evidence of prehistoric activity might be present in the general locality.

1.3. Close by to the south, the predicted line of a Roman road (PRN 93605) has been identified, though the possibility that any remains of a road/trackway could be of post medieval origin and related to the Bodrhyddan Estate has also been suggested.

2 Objectives 2.1. The objectives of the evaluation are:

 to reveal by means of a desk-based study and geophysical survey, the nature, condition, and significance of heritage assets within the area of the proposed development in so far as these aims are possible;  to identify any potential impacts on designated heritage assets in the locality  to record any heritage assets identified during the assessment;  to prepare a report outlining the results of the assessment.

3 Methodology 3.1. The evaluation will be conducted according to the Chartered Institute for Archaeologists’ (CIfA) Standard and Guidance for Archaeological Field Evaluation (2014) and Standard and Guidance for Historic Environment Desk-based Assessment (2014).

Desk-based Assessment

3.2. Stage 1 of the assessment will involve the examination of all the readily available primary and secondary sources at the following repositories:

 the regional Historic Environment Record  the National Library of Wales, Aberystwyth  the National Monuments Record, Aberystwyth  Denbighshire County Archives  Flintshire County Archives  LiDAR data

3.3. All cartographic sources consulted will be included within the desktop section of the report, together with transcriptions of relevant documents and copies of plans, maps and photographs containing relevant information, subject to any copyright restrictions.

Geophysical Survey 3.4. A magnetic gradiometer survey will be undertaken by Archaeological Survey West across the whole of the application area using a Bartington 601 two sensor instrument. The sampling interval will be at 0.25m on traverses 1m apart. All results will be presented in a report with full analysis and interpretation of appropriately filtered data. All raw and published data will be retained within the archive and submitted to the HER and NMR along with a high resolution digital copy of the final report.

3.5. The survey will adhere to the guidance set out in Historic England (2008) Geophysical Survey in Archaeological Field Evaluation and CIfA (2014) Standard and Guidance for Geophysical Survey.

4 Baseline Assessment 4.1. This will summarize the history of the site and the state of current knowledge regarding the nature, extent and degree of survival of the cultural heritage within the development area. It will include an assessment of the significance of any assets in a regional and national context.

4.2. Relevant aerial photographs, re-plots and historic maps may be included where appropriate, subject to any copyright restrictions. The report will include a location plan, together with mapping depicting the distribution of assets within the development area. A gazetteer of these assets will be included as an appendix, including details of NGR, site type, period and significance.

Assessment of Impacts 4.3. The assessment will consider potential direct impacts on all heritage assets within the development boundary in accordance with Welsh Government’s (2017) Heritage Impact Assessment in Wales.

4.4. The assessment will also consider potential visual impacts on all designated or registered heritage assets and their settings within 500m of the development boundary, based on the principles laid out by Welsh Government’s (2017) Setting of Historic Assets in Wales.

Report

4.5. Following the on-site work an illustrated report will be prepared containing conventional sections to include:
