AAP No.: 1
Townland: Abbotstown
Parish: Castleknock
Barony: Castleknock
Classification: Mound
NGR: 309153, 238742
Dist. from development: To the immediate north-west of Orbital Sewer
Description: The mound is planted with two mature trees that formed part of the designed element of the demesne associated with Abbotstown House (BH 4, DL 1). The 25 inch edition OS map of 1905 shows trees at this location. It is possible that the mound just represents a demesne feature. However, it may possess a greater antiquity and was then later utilised within the designed element of the landscape. The mound measures 33m north-east– south-west by 27m north-west–south-east. It has a maximum height of 1m and occupies a gentle south facing slope. Recorded church and graveyard AH 1 is located c. 65m to the north-east.

32102902/EIAR/3B Environmental Impact Assessment Report: Volume 3 Part B of 6
AAP No.: 2
Description: Two structures are marked in this approximate location of Rocque’s map of County Dublin in 1760 but not shown on later historical mapping. The structure is named as Hillbrook, although the first edition shows a house named Hillbrook in 1838 to the south (UBH 1). The SMR contains a record (DU014-051) that pertains to Sheephill demesne, although it has no known location. This is record is for a house site and may relate to the house shown on Rocque’s map. Today the area is almost completely covered by mature trees and shrubs. A large mound orientated north-south, does protrude from the tree line, although this appears to be a natural topographic feature, rather than something relating to the site of a post medieval house.

Classification: Possible enclosure site
NGR: 310154, 239627
Dist. from development: 0m (Orbital Sewer)
Description: The first edition OS map of 1838 shows the townland boundary forming a distinct oval at this location, which is also visible as a crop mark on the aerial photographic coverage. It measures c. 75m WNW-ESE by c. 60m NNE-SSW. It is possible that the curve was created by a water course and is completely natural. However, it may represent an enclosure site, which was avoided during the laying down of the boundary. Today there are no upstanding remains of the site as the boundaries have been removed and the field is under arable cultivation.

Parish: Castleknock
Barony: Castleknock
Classification: Site of Cappoge House
NGR: 311176, 240085
Dist. from development: To the immediate north of Orbital Sewer
Description: A house is marked at this location on Rocque’s Map of 1760, Taylors Map of 1816 and the OS map editions. It is named as ‘Cappoge’ on the first edition OS map and possesses elements of a designed landscape (DL 12). The later OS editions show the house as being slightly large with more outbuildings. Today any upstanding remains have been demolished.

Classification: Two tree rings
NGR: 309903, 239266 & 309972, 239265
Dist. from development: 0m (Orbital Sewer)
Description: Two small tree rings, likely to be directly associated with the demesne landscape associated with Abbotstown House, are shown at this location on the 1909 OS map (not apparent on earlier editions). The rings are also visible within the 2002 google earth mapping. Whilst likely to be post medieval in date, it remains a possibility that existing enclosures were utilised within landscape at design features.

Classification: Drumlin
NGR: 311896, 241018
Dist. from development: 0m (Orbital Sewer)
Description: As one of few areas of high ground in the landscape, this topographical feature may well have been seen as an attractive settlement area. The summit of the drumlin has been quarried out, which commenced in the 19th century as a small sand pit is marked here on the first edition OS map of 1838. However, if it was utilised as a settlement site, there may well be associated features on the slopes of the drumlin. The summit has a diameter of c. 60m. Examination of the 2013 Google Earth aerial photographs of the site has shown a possible curvilinear feature as a crop mark travelling around the southern part of the summit. This feature is located c. 25m east of the pipeline wayleave.

Barony: Coolock
Classification: Proximity to AH 15 & AH 34 (field system & enclosure)
NGR: 314228, 241592
Dist. from development: Orbital Sewer passes through this area
Description: This area consists of pasture, which is located to the immediate south of the zone of archaeological potential that surrounds recorded field system site AH 15. It is possible that the recorded site represents the remains of a small medieval settlement. One linear earthwork extends into AAP 8, which runs in a north-south direction. The earthwork is likely to represent a former boundary. It is possible that other former boundaries extend into AAP 8 from the site to the north, but possess no surface expression. To the south of the pipeline corridor and only recently added to the RMP is AH 34, which is a large enclosure identified from aerial photographs. The edge of the enclosure is located c. 20m south of pipeline wayleave.

AAP No.: 9
NGR: 314692, 241616
Dist. from development: Orbital Sewer crosses the watercourse
Description: This watercourse is marked on the historic OS mapping and eventually forms the Santry River further to the south-east. It consists of a substantial stream, which has created a small valley. The sides of the stream slope steeply to a gravel base with a good flow of water. The water course is flanked by dense and mature vegetation. The first edition OS map of 1838 shows a small channel to the immediate east of the stream where it will be crossed by the pipeline. The channel is shown with a total length of c. 60m and appears to run from a square pond at its northern end. It is not clear as to the function of this feature. However, it may represent a natural spring, the flow of which was directed into the main stream. No evidence of an extra channel was noted during the field inspection. However, to the east of the stream an area of rough, water logged ground was noted, slopping gently to the west, which can also be considered to possess archaeological potential as it is an ideal location for burnt mound (fulachta fiadh) activity. The area was very overgrown with sedge grass and brambles, so no obvious upstanding archaeological remains were noted. The water logging may have resulted from the presence of the spring marked on the first edition.

Classification: Enclosure
NGR: 319406, 242087
Dist. from development: Within the WwTP
Description: The site of a sub-circular enclosure was identified during a geophysical survey of the proposed WWTW site at Clonshagh. The enclosure is located to the immediate north of the red line boundary of the site and to the immediate south of a stream, which also functions as a townland boundary. It has a diameter of c. 47m, although the northern part of the enclosure extended beyond the limits of the enclosure. Field inspection confirmed that there are no upstanding remains associated with the enclosure, which occupies a slight north facing slope.
Archaeological testing was carried out at this location in February 2016. Whilst two potential ditch cuts were identified in the vicinity of the geophysical response, both had been impacted upon by the insertion of land drains and both locations filled with water, which prevented the

Classification: Enclosure
NGR: 320101, 241978
Dist. from development: c. 150m east of WwTP
Description: The site of a possible enclosure is located within the grounds of Springhill House (BH 14, DL 4). It is marked on the first edition as a tree ring within the demesne associated with Springhill House. It is possible that it was originally established as a tree ring. However, when considering the proliferation of enclosures in the surrounding area, it could have already been present within the landscape and then utilised within the demesne as a design feature. The outline of the enclosure is visible on the 2008 Google Earth coverage. It is oval in plan and measures c. 37m north-south by c. 29m east-west. There are no upstanding remains.

Parish: Kinsaley
Barony: Coolock
Classification: Area of water logged ground
NGR: 321850, 242039
Dist. from development: 0m (Orbital Sewer)
Description: An area of water logged ground was noted during the field inspection in the southern portion of the townland of Kinsaley and to the immediate north of the townland boundary (TB 21). The first edition OS map of 1838 shows a stream running through this area, to the north of the townland boundary. That stream is not present as a water course today, but based on the water logged conditions and shoulder height reeds and sedges, it is clear that water passes through the area. The presence of water course means that the area has the potential to contain the remains of burnt mound (fulachta fiadh) activity. No standing archaeological remains were noted during the field inspection.

landscape (DL 21). The house is shown with its main elevation facing south, with a number of outbuildings to the north and north-east. The entrance drive comes from the south. Based on the first edition OS map, the northern part of the site of Wellfield Cottage will be located within the pipeline corridor, along with the site of associated outbuildings. Today the site is under arable cultivation and there are no upstanding remains of any features. The house was demolished and the demesne was incorporated into the larger demesne associated with St Doolagh’s Park (BH 25, DL 20) after 1850.

Classification: Enclosure
NGR: 322768, 241706
Dist. from development: c. 53m south of Outfall Pipeline – land-based
Description: The site of two enclosures, one overlying the other, was identified within the 2013 Google Earth aerial photographs of the area as crop marks. The larger of the two enclosures measures c. 45m north-south by c. 34m east- west and is oval in plan. A smaller circular enclosure overlies, or is overlain by, the western part of the larger enclosure. This has a diameter of c. 23m. The site may represent multiple phases of early medieval activity, or may even represent multi-period activity. It is further possible that this site and AH 47 to the north are associated with one another. Field inspection confirmed that there are no upstanding remains of either enclosure.

Barony: Coolock
Classification: Coastal area & proliferation of archaeological sites
NGR: Large area – see figures
Dist. from development: Outfall Pipeline – land-based travels through this area of potential
Description: This area of archaeological potential has been designated due to the proximity of the coast and the high concentration of archaeological sites. Coastal areas have always been attractive for settlement throughout prehistoric and historic periods. As such, the likelihood of finding archaeological remains within this area is higher than with a regular inland greenfield site. In addition there are six recorded archaeological sites within this area, which consist of a ring ditch (AH 44) and six enclosures (AH 43, 45, 46, 28, 27, 47). These are likely to represent high density early medieval occupation of the area, whilst the ring ditch may be Bronze Age or Iron Age in date. A further large enclosure site have also been identified within the aerial photographic coverage of the area (AAP 18). The eastern part of the area is formed by a spit of land located within the townland of Burrow. This is characterised by sand dunes and Portmarnock Beach. Between the spit and the main land, the River Sluice and Mayne discharge into a coastal salt marsh, which is characterised by marsh vegetation and meandering watercourses. The whole area should be considered to possess high archaeological potential.

Appendix A16.6 Designed Landscapes Located Within the Receiving Environment A desk based assessment of demesnes and gardens within the County Dublin has been completed by the NIAH. This was reviewed as part of this assessment to gain an insight into the possible significance of the surviving demesnes within the receiving environment of the proposed scheme. Twenty-six designed landscapes or demesnes are located within the receiving environment.
A total of 16 of these (Cappoge House, Kildonan House, Dubber House, Ballymun House, Edendale, Upper Middleton, Lower Middleton, Kinsaley House, St. Doolagh’s Park, Wellfield Cottage, Snugborough Cottage, Merton, Drumnigh Lodge, Mayne House, Silloge House and Heathfield House) are not included within the survey.
The NIAH Site Survey Report includes:
Initial Overview: general comment on the overall site and impact of any recent development;
Architectural Features: the presence and survival of the principal buildings and other structures such as gatehouses and garden buildings.
Movement within Site: the presence of drives, walks and avenues and changes in these since the maps were made.
Landscape Features: the presence of key features such as walled gardens, woodland, orchards, formal gardens, vistas, lakes and rivers. A short comment will normally be provided on the character and condition of the landscape.
In the Initial Overview there is a reference to the Feature Richness Index. This is a figure that can range from 1 to 16 and represents the total number of major traditional garden features identified. It could be a high figure for a site that is partially destroyed, but could also be a low figure for a site that is virtually complete and unchanged. The Feature Richness Index is not an indication of heritage significance or merit. It should also be noted that features could survive that are not visible on the aerial photography as this is only a desk based assessment (NIAH survey, www.buildingsofireland.ie).
There are five possible options identified for the Statement of Condition:
Main features substantially present: - no loss of integrity
Main features substantially present: - some loss of integrity
Main features substantially present:- peripheral features unrecognisable
Main features unrecognisable: - peripheral features visible
Virtually no recognisable features

Comment: Edendale House is marked on the first edition OS map within a small demesne, which is surrounded by tree belts. A garden is shown to the west of the house along with outbuildings. There is a gate lodge marked at the entrance to the demesne. By the time of later map editions little has changed although the planting is no longer marked on some of the maps. Today the principal house has been removed and the outbuildings are ruinous. A modern house is located within the demesne and the gate lodge has also gone. However, the mature tree belts still surround the original demesne and make the layout easy to distinguish.

Comment: The main house was constructed in 1850 and as such is not marked on the first edition. The demesne incorporated elements of the existing landscape associated with St. Doolagh’s Lodge, located just outside of the receiving environment. It also included the demesne and site of Wellfield Cottage (DL 21), which is present on earlier mapping. Today the main house survives, along with some tree belts. However, the area surrounding the house has been impacted upon by modern development and the landscape to the east has lost its demesne character and been subsumed back into an arable landscape.

By the time of the first edition OS map the house and one outbuilding is shown with a possible orchard to the east. It is not named on the map. Many of the boundaries are planted with trees, giving an indication of design rather than a specific demesne landscape. Today the house has gone and the ruins of one shed survive along with some modern derelict farm buildings. Mature planting survives along the boundaries surrounding the built remains.

NGR: 309414, 238581
Dist. from development: c. 175m southeast of the Orbital Sewer
Description: This building is a country house that is first shown on Rocque’s Map of County Dublin in 1760 and then again on Taylor map of 1816. It is shown in detail on the first edition OS map, within a shaded demesne landscape (DL 2), with outbuildings and walled gardens to the east of the main structure. The main facades face to the east and south, with driveways shown to the house from the south-west the north-east. By the time of later OS mapping, the structure has been extended to the north. Today the house survives, but has lost much of its attendant grounds due to the construction of the M50 and Dunsink Lane c. 50m to the west. The gardens have been removed, along with the entrance drive and southern gate lodge. Inspection of the actual property during the field inspection was not possible as it is privately situated and screened fully by trees. However, the desk based resource suggests the structure occupies the same footprint as during the late 18th century and retains some of its outbuildings to the west.

NGR: 309321, 238842
Dist. from development: Within the Orbital Sewer (tunnel)
Description: This is a section of demesne wall associated with the Abbotstown House demesne (BH 4, DL 1). Prior to the construction of the M50, the wall ran from an entrance into the demesne at the recorded graveyard site (AH 2, BH 2) in an easterly direction on the northern side of a small road that ran between the demesnes of Abbotstown to the north (DL 1) and Hillbrook to the south (DL 2). The construction of the M50 has resulted in the removal of a large portion of the wall and the south-east portion of the demesne lands. The surviving section consists of random rubble masonry and roughly dressed coping stones, which survive to a height of c. 2m. The wall is very overgrown and has collapsed in places. There is no evidence for a gate lodge at the entrance to Abbotstown, as marked on the first edition OS map. However, the pillared gateway into the demesne, which is marked on the later OS map, is still present.

Description: The construction of the Dublin-Drogheda railway was completed in 1944, although the path of the railway is marked on the 1838 OS map edition as being ‘in progress’. The bridge is not clearly marked on this map, although its position across the road is indicated. Today the bridge consists of coursed masonry abutments spanned by a metal structure to form a square arch. This has been added to with reinforced concrete in recent years. The bridge is skewed across the road in order to maintain the straight nature of the line.

Description: This townland boundary is marked at the same location on all the OS map editions. It is formed by a small stream, which is not marked on the first edition, but shown on later OS maps. To the south-east of where the wayleave will cross the boundary, the water course has been culverted to flow beneath the M50. The section to be crossed by the pipeline wayleave consists of a mature, multi-species hedgerow, with a small water course flowing adjacent to the hedge on the north-eastern side. The flow of water was moderate at the time of the field inspection. The presence of a water course within this boundary lends archaeological potential to the area.

Description: This townland boundary also functions as a parish and a barony boundary. Within the historic mapping it is shown as following what is now the R122. At the location where the pipeline will cross this road, it formerly ‘kinked’ slightly, which has since been straightened. As such, the road (at this particular location) deviates from the original boundary for a small distance. The road, which is a busy route way, has been widened in the past, but still appears to travel within the same corridor as depicted on the first edition OS map of 1838. It is flanked by a mixture of denuded hedgerows and modern agricultural fencing.

Description: The pipeline wayleave will cross two boundaries within a relatively short distance and these separate three townlands and two parishes. The section that separates Commons from Dardistown is formed by a road that today travels between the airport to the north and Santry to the south. This road is present on all the historical mapping, but today has been significantly widened due to the amount of traffic it carries. From the road, the boundary turns east. Today the boundary flanks the entrance to a modern cemetery. It has been impacted upon by ongoing road works in the area, but the majority of it is intact and formed by a ditch and mature hedgerow and trees. At the eastern end of the boundary it meets the townland and parish boundary that separates Commons and Dardistown (within the Parish of Santry) from Toberbunny (Cloghran Parish). The section of boundary within the pipeline wayleave has been partially removed, with the remainder formed by a denuded hedgerow with interspersed mature trees.

The remainder of the WWTW site is also located with Clonshagh, but this is situated in the Parish of Santry. It is not clear why such a small parcel of Clonshagh was left within Cloghran. A boundary surrounds this portion of land and also separates Burgage from Clonshagh to the east and Middletown to the north. The boundary is formed by a mature hedgerow and ditch, interspersed with mature trees, which surrounds the entire field. The boundary on the northern side is formed by a denuded hedge line and a stream within a relatively deep cutting to the immediate north. The flow of water was moderate at the time of the field inspection. The presence of a water course within this boundary lends archaeological potential to the area.

TAG PROJECT 13003, REGIONAL WASTEWATER TREATMENT PLANT (APPENDIX 1 TECHNICAL REPORT), GREATER DUBLIN DRAINAGE, NORTH COUNTY DUBLIN As part of the selection process for the site of a proposed Regional Wastewater Treatment Plant (WwTP) for the Greater Dublin Drainage scheme geophysical surveys were conducted across 3 land parcels in North County Dublin, in Clonshagh, Annsbrook and Newtowncorduff townlands. The Clonshagh site Site Location traverses 23ha of agricultural located at the northern perimeter of Dublin City, 2km north‐east of the M1 interchange with the M50 and N32. Belcamp College lies 0.7km to the south‐east, and Dublin Airport 2km to the north‐west. The Annsbrook and Newtowncorduff sites comprise 2 land parcels, respectively 20 and 23ha in size, 11.8km north of Clonshagh, situated east and west of the M1 Motorway, 3.3km and 1.4km west of Lusk, 7km north of Swords.

6 RMPs lie within 1km of the Annsbrook and Newtowncorduff sites, including field system DU008‐066; pit burial DU007‐034; burnt pit DU007‐035; windmill DU008‐007; moated site DU008‐016; and fulacht fiadh DU008‐069. Cultural heritage sites identified within 1km include 2 mounds (CH11); possible ring ditch CH12; possible mill and castle CH23; possible medieval settlement CH25; a possible earthwork associated with the site of Annsbrook House (CH26); part of mill race CH89; and Woodpark House and corn mill CH90 & CH62. Method Fluxgate gradiometry
SURVEY OBJECTIVE The purpose of the geophysical surveys in Clonshagh, Annsbrook and Newtowncorduff was to define the nature and extent of archaeological remains where present at each site. The results from this work will be used to inform on the identification of a preferred site for the proposed regional WwTP.
SUMMARY OF RESULTS One concentration of archaeological remains has been recorded to the south‐west within the Newtowncorduff land parcel, in NG3. This comprises a magnetically strong sub‐rectangular ditched enclosure, with adjoining linear/curvilinear responses suggesting the presence of further enclosure remains. Combined the remains identified in NG3 extend over an area c.50m north/south by c.77m east/west.

One circular ditched enclosure, measuring c.40m in diameter, has also been located at the northern edge of the Clonshagh land parcel, in CG3. No further concentrations of definite archaeological response have been recorded from survey within the investigation boundaries at Clonshagh, Annsbrook and Newtowncorduff.
Two concentrations of response, which may represent a levelled enclosure or structural remains, have been recorded within the investigation boundary at Annsbrook, to the north‐west (AG1), and south‐ east (AG7). The remains of a possible early field system have also been recorded to the south within the investigation boundary at Clonshagh in CG2 a possible rectangular enclosure also indicated the south‐eastern edge of CG2.
The results from survey demonstrate patterns of former landuse, including remains of possible early field systems, alignments of more recent disused boundaries, past cultivation and recent land drains.
Numerous weak trends are also present throughout the survey results. The potential that some of these may represent plough damaged/shallow remains of archaeological interest should not be dismissed. However, the majority are expected to derive from natural soil/geological variations.
One area of natural soil/geological variation has been recorded to the south‐east in the Newtowncorduff land parcel, in NG9.

1 SURVEY METHODOLOGY
1.1 METHODOLOGY This geophysical investigation employed fluxgate gradiometry to investigate all available lands within the Clonshagh, Annsbrook and Newtowncorduff land parcels. The survey covered a total of 21 areas at Clonshagh (CG1‐CG5), Annsbrook (AG1‐AG7) and Newtowncorduff (NG1‐NG9). The following gradiometer instrumentation and sampling strategy was used for this survey:
Instrumentation Traverse Interval Sample Interval Ha
Bartington Grad601 4 sensor gradiometer cart 1m 8‐10 per m (10Hz) 49 system combined with GPS
1.2 POSITIONING OF SURVEY DATA A Trimble VRS Now GPS was used to record GPS locations to a precision of 20‐40mm (horizontal and vertical) at a rate of 1Hz along each instrument traverse. These coordinates were subsequently used for positioning of the gradiometer data. Further alignment to Irish National Grid was facilitated by tie‐ in coordinates at the start and/or end of each survey block.
1.3 DATA PROCESSING Processing of survey data was undertaken using in‐house software and GRASS GIS as follows:
Data Processing Positioning of gradiometer data according to GPS measurements (in‐house) Gradiometer data de‐drift, zero median traverse & clip (in‐house) Gradiometer data gridding by inverse distance weighted surface interpolation (GRASS GIS) Bicubic spline surface interpolation of gradiometer data (GRASS GIS) Extraction of ferrous anomalies via SQL query of GIS database table (GRASS GIS)

2 GENERAL CONSIDERATIONS
2.1 ACCESS Ground conditions within the Annsbrook and Clonshagh land parcels were generally good, both locations being mainly available for survey. Waterlogged and difficult ground precluded fieldwork to the north and south‐east at the Annsbrook land parcel, and also within one cultivated field at the centre of the Clonshagh land parcel.
© Target Archaeological Geophysics Client Fingal County Council. TAG 13003 ‐ Regional Wastewater Treatment Plant (WwTP), Greater Dublin Drainage, North Co. Dublin 4
Fieldwork within the Newtowncorduff land parcel was completed in two stages: stage 1 across the relatively dry, pasture to the west; stage 2 resuming in the eastern portion of the site after a drying out period of c.3 weeks. Two small areas containing a dense cover of trees at the northern Newtowncorduff survey perimeter remained unavailable for investigation throughout.
Survey to the limits of each field at the Clonshagh, Annsbrook and Newtowncorduff sites was not always possible due to ground disturbance from machine access during geotechnical investigations.
2.2 SOURCES OF MODERN INTERFERENCE The survey results contain numerous small‐scale and larger concentrations of ferrous response. These are frequently recorded in gradiometer surveys and often caused by modern metallic debris contained within the topsoil or at the ground surface. Large‐scale ferrous responses in the data derive from survey in proximity to adjacent fences, boundaries and modern surfaces. Interference from one electricity pylon bordering Newtowncorduff survey locations NG3 and NG4 was noted. The potential that the interference from this electricity pylon may have masked responses of archaeological significance should not be dismissed.
Ferrous anomalies from each block of survey data have been extracted by highlighting all readings beyond the +/‐15nT range and exporting these values in shapefile format. This has been achieved via a SQL query of the attribute table in the GIS. This data has subsequently been manually edited in AutoCAD with reference to the greyscale displays for each survey block.
Ferrous responses recorded from this survey are not referred to in the results section of this report unless deemed relevant.

3 FLUXGATE GRADIOMETRY RESULTS
3.1 CLONSAGH SITE
3.1.1 CG1 The results from CG1 display a relatively quiet magnetic background with no characteristic archaeological type responses evident. Several weak linear trends extend across the survey centre and to the north, notably anomalies 1 which are oriented north‐east/south‐west and north‐ west/south‐east. These anomalies could represent plough damaged responses of archaeological interest. However, they are located at the edge of the investigation perimeter, and the absence of any definitive archaeological patterns in CG1 suggests they derive mainly from natural sources of variation and/or more recent landuse.
A band of elevated positive response in CG1 to the north of the survey perimeter represents natural soil/geological variation in proximity to a stream.
No anomalies of definite archaeological character have been identified in CG1.
3.1.2 CG2 The results from CG2 display a series of curvilinear positive anomalies and connecting trends to the north‐west (2) and east of survey centre (3). Responses 2 and 3 may represent the remains of an early field system. Part of a possible ditched enclosure (4) is indicated at the south‐eastern survey edge.
Remains of disused boundaries (5) extend from survey centre to the north‐east and north‐west, with north‐west/south‐east and north‐east/south‐west former cultivation also indicated.
Further weak trends apparent throughout CG2 are expected to derive from patterns of former cultivation, natural soil/geological variation and possible former land divisions. The potential that a number of these could represent eroded or magnetically weak archaeological remains should not be dismissed.
No further anomalies of note have been recorded in CG2.
3.1.3 CG3 Part of a sub‐circular enclosure (6), measuring c.40m in diameter, has been recorded at the north‐ eastern limit of CG3. This intersects with the northern site edge by c.2.5m. No responses of archaeological significance have been recorded within the site boundary in association with anomaly 6.
One weak trend (7) traversing the approximate centre of CG3 roughly east/west may represent the remains of a former boundary. Further weak trends have been recorded, notably anomalies 8 to the east of survey centre. These may be significant, although the absence of any definite archaeological patterns in this location suggests a natural or more recent landuse origin is more likely.
A series of circular fluctuations in response traversing CG3 north‐west/south‐east represent magnetic disturbance from overhead electricity cables.
Natural variation in proximity to the stream bordering the northern site edge continues beyond the site boundary.
No further responses of interest have been recorded from survey in CG3.
3.1.4 CG4.1, CG4.2, CG4.3 The results from CG4.1 indicate a series of possible land drains (9) aligned east/west to the north, and weak linear trends, notably anomaly 10, to the south of survey centre. Similar weak trends extend through CG4.2, notably anomaly 11 to the south of survey centre, and in CG4.3 to the north eof th
© Target Archaeological Geophysics Client Fingal County Council. TAG 13003 ‐ Regional Wastewater Treatment Plant (WwTP), Greater Dublin Drainage, North Co. Dublin 6 survey limit. These weak linear trends may be archaeologically significant. However, the absence of any characteristic archaeological patterns suggests they most derive likely from further drainage features, cultivation or natural soil/geological variation.
No responses of archaeological character have been recorded in CG4.1, CG4.2 and CG4.3.
3.1.5 CG5 The remains of a possible former boundary (12) are indicated by weak trends extending roughly east to west across the northern portion of CG5. Intersecting land drains (13) have been recorded to the north‐east and numerous weak linear trends (14 & 15) are also apparent, mainly to the north‐west. Anomalies 14 may be significant, potentially representing plough damaged enclosure or magnetically weak linear remains, which extend partly beyond the north‐western survey limit in CG5.
Further possible boundaries are indicated by weak trends 15 extending north to south and east to west across CG5. Weak trends indicated elsewhere through CG5 are expected to derive from patterns of former cultivation and or natural soil/geological variation.
Remains of former cultivation aligned east to west are indicated to the south in CG5.

3.2.1 AG1 The results from AG1 display a low level of response throughout. One isolated positive anomaly (16), potentially a pit, has been recorded to the west. One former boundary and a possible former boundary are indicated on a north/south alignment at survey centre and to the east (17 and 18).
The remains of a possible plough damaged enclosure or levelled structure are indicated to the north‐ east in AG1 by zones of increased response, positive anomalies and weak trends (19). These traverse an area c.30m east/west and are located close to the northern site limit. Two potential pits (20) are indicated c.20m south of 19. Interpretation of anomalies 20 is tentative as they are small‐scale, and could derive from natural sources of interference, recent landuse or modern ferrous.
A network of land drains (21) aligned roughly north‐west/south‐east extends across the eastern portion of AG1. Further weak trends in the results are deemed of limited significance, likely the result of recent landuse and/or natural soil/geological variation.
No further anomalies of interest have been recorded within AG1.
3.2.2 AG2 No responses of archaeological significance have been recorded from survey in AG2. Land drains highlighted as anomalies 22 extend east/west and north‐west/south‐east throughout the survey block. Remains of former cultivation are also visible in the results mainly on the similar alignment.
3.2.3 AG3 Further north‐west/south‐east land drains (23) are apparent in AG3, intersecting with the remains of a former boundary indicated by a series of north‐east/south‐west oriented ferrous responses (24).
One single positive response (25) at the north‐western edge of AG3 may be significant, potentially representing the location of an isolated pit. Interpretation of anomaly 24 remains cautious as there are no clear representations of archaeological features in the data set and it is possible that this response could derive from modern ferrous material contained within the topsoil.
No further responses of note are visible in the results from AG3.

3.2.4 AG4 Land drains aligned north‐west/south‐east extend throughout AG4 and are indicated as anomalies 26. Three weak linear trends, notably 27, are apparent on the same alignment to the east, north‐east, and south‐east of survey centre. These are deemed to be of limited archaeological interest, and are likely representative of recent patterns of landuse.
No anomalies of archaeological significance are indicated by the results from AG4.
3.2.5 AG5 Land drains highlighted as anomaly 28 are visible on north‐west/south‐east alignment in AG5.
No further responses of note have been recorded in AG5.
3.2.6 AG6 Land drains highlighted as anomalies 29 on north‐west/south‐east and north‐east/south‐west alignments extend throughout AG6.
Three isolated positive anomalies (30, 31 & 32), occasionally bound by weak trends, are evident in the results from AG6 to the north, east and south‐west of survey. These may represent isolated linear/sub‐angular features of interest. Interpretation remains cautious as the results from AG6 display no definite archaeological patterns.
The remains of a possible former boundary (33) are indicated north of survey centre by a weak linear trend aligned north‐west/south‐east. A further possible former boundary aligned approximately north/south is indicated by two weak trends extending through the south‐eastern portion of AG6.
Weak parallel linear trends (34) east of survey centre in AG6 are thought to represent machine tracks from recent geotechnical studies.
No further responses of note have been recorded in AG6.
3.2.7 AG7 One area of increased response (35) to the west of survey centre in AG7 may represent a possible levelled structure or concentration of plough damaged linear/pit remains. This area of response contains numerous overlapping weak linear trends and two isolated positive responses and may represent remains associated with the site of Annsbrook House (CH26).
One possible former boundary (36) is indicated by a weak trend on north‐west/south‐east alignment traversing the southern edge of AG7.
Land drains aligned north‐west/south‐east extend throughout AG6 as anomalies 37.
No further responses of note are indicated by the results from survey in this location.
3.3 NEWTOWNCORDUFF SITE
3.3.1 NG1 The results from NG1 display a low level of background variation. Weak linear trends (38) extend from the centre of survey to the north and east. These are at the limits of instrument detection, and likely the result of variations from natural soil/geological variation.
No further anomalies of interest have been recorded in NG1.

3.3.2 NG2 Remains of former cultivation aligned roughly east/west extend throughout NG2. Weak linear trends are also apparent at survey centre, to the north‐east and east (39). The potential that these may be significant should not be dismissed, although a natural/cultivation origin is more likely.
No further anomalies of interest have been recorded in NG2.
3.3.3 NG3 The results from NG3 indicate an enclosure complex defined by a sub‐rectangular arrangement of magnetically strong linear ditch remains (40), with peripheral curvilinear anomalies to the south‐east (41), and weak trends to the east, south‐east, west, and south‐west. Combined these anomalies extend c.50m north/south by c.77m east/west. There are no clear indications in the data of pit type anomalies or hearth remains in proximity to anomalies 40 and 41, suggesting that the remains identified could potentially possess a ceremonial rather than settlement context.
No further anomalies of interest have been recorded in NG3.
3.3.4 NG4 Two positive anomalies and peripheral weak trends extend through NG4 to the south (42) and west (43) of survey centre. These may be of interest. They are located more than 75m to the south of the enclosure complex identified in NG3and situated on sloping uneven ground. A potential soil/geological origin for these anomalies should not be dismissed.
No further anomalies of interest are apparent in the results from survey in NG4.
3.3.5 NG5 One isolated positive anomaly (44) is apparent to the north‐east of survey centre in NG5. This response is very small‐scale and expected to represent deeply buried ferrous contained within the topsoil.
Weak linear/curvilinear trends are visible to the east and west of survey centre (45). These anomalies correspond to shallow variations in topography noted at the time of fieldwork.
A former boundary is indicated by linear anomaly (46) traversing the centre of NG5 approximately north/south.
A possible further boundary indicated by weak trend 47 is apparent on approximate east/west alignment to the south of survey centre, and this intersects with anomaly 46.
No further responses of note are visible in the results from survey in NG5.
3.3.6 NG6 Small‐scale positive anomalies, such as 48, are visible to the east, at survey centre, and to the south‐ west in NG6. These are very insubstantial and expected to derive from ferrous debris contained within the topsoil.
A former boundary (49) on approximate north/south alignment traverses the centre of NG6.
Weak linear and rectilinear trends are visible throughout NG6, notably to the west (50) and north‐east (51). These are at the limits of instrument detection. Anomaly 50 may indicate part of an early field system or drainage. The remaining weak trends in the data are largely expected to derive from natural variations in the underlying soils and/or geology.
Land drains (52) are visible in NG6 to the south‐east and north‐west.

No further responses of archaeological significance are apparent in the results from NG6.
3.3.7 NG7 The remains of a probable early field system are indicated by intersecting linear trends 53, which traverse NG7 north‐east/south‐west and east/west. Further weak linear trends extend through NG7, mainly to the north‐west and west (54), and these may remains of recent landuse or cultivation.
Several poorly defined small‐scale positive anomalies are indicated to the west (55) and south‐west. These may be of interest. However, they display no sufficient range of response or character to warrant an archaeological interpretation. These anomalies are thought to derive from modern ferrous or natural soil/geological variation.
Land drains (56) aligned approximately north ‐west/south‐east extend through the central portion of NG7.
No further responses of note are evident in the results from survey in NG7.
3.3.8 NG8 Part of a probable early field system (53) extends east to west through the southern portion of NG8. Further small‐scale positive anomalies, such as 57, are visible to the east and south‐east. These are small‐scale, poorly defined and expected to derive from natural variation and/or modern ferrous.
Land drains (58) extend mainly north‐west/south‐east through NG8.
Interpretation of weak linear trend 59 to the south is uncertain. This anomaly is not expected to be of archaeological significance, rather a result of more recent landuse, potentially a former drain or disused boundary.
No further responses of interest are visible in the results from survey in NG8.
3.3.9 NG9 Three isolated positive anomalies (60) have been recorded in NG9 to the south‐east, south‐west and west of survey centre. No definitive archaeological features are indicated by the results from survey in NG9. Anomalies 60 are expected to derive from modern ferrous and/or soil/geological variation.
A cluster of irregular positive/negative responses and weak trends (61) north‐east of survey centre is expected to derive from natural soil/geological variation. Further weak trends such as 62 to the north‐ west are indicative of low level interference from soil/geological sources. The potential that some of these anomalies may represent remains of former land divisions and effects from previous landuse should not be dismissed.
Remains of a former boundary (63) and part of a possible early field system (64) are evident traversing NG9 north‐east/south‐west and north‐west/south‐east through the southern portion of survey.
Weak linear trends 65 border the northern limit of NG9 and correspond to the present pattern of cultivation in this field. A slight instrument drift from zero during fieldwork is suggested by these anomalies during fieldwork in this location.
No further responses of note are indicated in the results from NG9.

4 CONCLUSIONS 4.1 The gradiometer surveys conducted in connection with the selection process for the site of the proposed Regional WwTP have recorded the location of one enclosure complex in the south‐western portion of the Newtowncorduff land parcel. These remains extend through NG3, are highlighted as anomalies 40‐41, and cover an area c.50m north/south by 77m east/west. A circular ditched enclosure, which just intersects with the northern limit of the Clonshagh land parcel, has also been identified in CG3, and is highlighted as anomaly 6. No archaeological responses associated with anomaly 6 are visible within the Clonshagh investigation boundary. One possible field system (anomalies 2 and 3) has been recorded to the south within the Clonshagh investigation boundary, and a possible rectangular enclosure associated with this is also visible to the south‐east.
4.2 Two further anomaly concentrations, which may represent levelled enclosure or structural remains, have been identified within the Annsbrook land parcel. These are located to the north‐west in AG1 (anomalies 19), and to the south‐east in AG6 (35). The responses are poorly defined; display no clear pattern or symmetry, and their interpretation remains uncertain. The potential that anomaly 35 may be associated with the site of Annsbrook House (CH26) should not be dismissed.
4.3 Isolated positive responses have been recorded within the Annsbrook and Newtowncorduff (NG4‐NG9) land parcels, notably anomalies 16, 20, 25, 31 and 32 in AG1, AG3, AG6 & AG7, and 42, 43, 44, 48, 55, 57 and 60 in NG4‐NG9. These are generally small‐scale and display no specific range of response or character to warrant a definite archaeological interpretation. The majority of these are expected to derive from natural soil/geological variation, modern ferrous and patterns of former landuse.
4.4 Remains of possible early field systems are indicated by the results from survey within the Clonshagh land parcel, in CG1 (anomalies 2, 3 4), and at Newtowncorduff in NG5‐9 (anomalies 47, 50, 53, 64). These are poorly defined, visible mainly as weak trends slightly above background variation, and their interpretation therefore remains tentative. The potential that anomaly 4 to the south‐east in CG1 represents part of a settlement enclosure should not be dismissed.
4.5 The results from survey contain numerous linear responses and weak trends deriving from patterns of recent landuse, including remains of disused boundaries, former cultivation and land drains.
4.6 One area of natural soil/geological variation has been recorded to south‐east within the Newtowncorduff land parcel, in NG9. Numerous weak trends of likely natural soil/geological origin are also present throughout the results from survey at Clonshagh, Annsbrook, and Newtowncorduff. The potential that some of these may represent plough damaged or shallow archaeological remains should not be dismissed.

© Target Archaeological Geophysics Client Fingal County Council. APPENDIX 1: TECHNICAL INFORMATION ON INSTRUMENTATION AND DATA
GEOPHYSICAL INSTRUMENTATION
GPR/Ground Penetrating Radar (GSSI SIR‐3000): GPR instrumentation comprises 1 central control unit for system configuration and data acquisition, a bistatic antenna (250‐500mhz for archaeological purposes), and either a cart or survey wheel fixed with an odometer. GPR transmits a continuous electromagnetic pulse or wave of energy into the ground dan records reflections of that energy following its interaction with buried objects and layers below the surface. Data is acquired along parallel transects or within a network of 20m2/30m2 grids with measurements recorded as a function of 2‐way travel time (the elapsed time for the energy wave to travel from transmitter to reflector and back to the surface). The strength of GPR reflections is proportional to the conductive and dielectric properties of the layers and objects with which the transmitted energy is incident.
Gradiometry (Bartington Grad601‐4 Sensor Combined Gradiometer & GPS array): Gradiometry is perhaps the most widely used technique in archaeological geophysics. A conventional gradiometer system comprises a data logger, and at least 1 fluxgate gradiometer sensor to map variations in soil magnetism caused by buried archaeological features. These variations derive from processes of burning activity and organic enrichment of the soil which occur during phases of archaeological settlement. Gradiometer surveys require survey across a network of 20m2/30m2 grids, or when integrated with GPS and a GIS data can also be collected along regularly spaced parallel lines of infinite length. The minimum recommended sampling routine for gradiometry is 0.25m x 1m.
Resistivity (Geoscan RM15 & Twin Probe Array): Resistivity is generally deployed to target known or suspected buried structures, including building foundations, walled enclosures, remnants of burial cairns, and existing earthworks. Using an array of electrodes mounted on a portable frame a small electrical current is passed through the ground at regular intervals via current emitting electrodes and the variations in resistance above background recorded via potential probes. Single or parallel twin resistivity systems use a pair or 2 pairs of current and potential probes mounted on a mobile frame with 1 remote current and 1 potential probe maintained at a stationary location no less than 20m from the survey limit. Standard resistivity sampling intervals are 0.5m x 0.5m, 0.5m x 1m or 1m x 1m, with use of either sampling routine specific to the size and depth of the suspected target(s).
DATA DISPLAY
Greyscale: The greyscale format assigns a cell to each datum according to its location on the grid. The display of each data point is conducted at very fine increments, allowing the full range of values to be displayed within the given data set. This display method also enables the identification of discrete responses barely above background levels of natural soil magnetism.
XY Trace: XY Trace displays provide a near‐perspective representation of responses recorded along each instrument traverse. This display format is primarily used for identifying modern ferrous material, but can be informative on location of hearth, kiln and furnace remains, where strong magnetic responses may otherwise be dismissed as modern ferrous in origin. Responses from modern ferrous material can alternatively be identified by extracting readings beyond a specified range (e.g. +/‐15nT) within a GIS, and then editing this geo‐referenced data over greyscale displays.
Time‐slice: Radargrams collected from survey along a grid can be compiled as a 3D volume, then resampled to produce a series of 2D plans at incremental depth/time offsets. A series of Time‐slice displays at 25‐50cm offsets permits analysis of the varying pattern and depth of responses within a given survey area.
