  Description

  Eighteen potential archaeological sites were found during monitoring of topsoil-stripping on the Celbridge Interchange, from April to December 2001 (Licence no. 01E0306). The scheme was approximately 4km in length and ran from Celbridge to Leixlip through gently undulating land with a mixture of arable, pasture and woodland. The southern part of the scheme runs through an area heavily influenced by 18th-century landscape design, with avenues, woodland and tree-lined field boundaries centred on the early 18th-century house at Castletown. The site (Site 14), a pit, was first seen in section on the eastern side of the deeper, central area of the excavated carriageway, approximately 0.45m below present ground level. An oval, stepped cut, with slightly concave sides, 1.9m in total length and 1.25m wide, cut the natural and was truncated on its western side by the track machine. It was 0.2m deep at its eastern end and 0.33m at its western. The base was distinctly stepped. The cut was filled in the deeper, western end by a soft, mottled black and red charcoal deposit. This was sealed by a deposit with less charcoal but with fragments of animal bone. It covered the entire area of the cut but sloped downwards to the west. Over this was a friable dark brown sandy clay with frequent charcoal flecks and animal bone. It covered the entire cut and was the final fill. Post-medieval pottery sherds, a nail and a gold ring were found in the topsoil. (www.excavations.ie) Compiled by: Gearóid Conroy Date of upload: 10 June 2011

  Description

  Eighteen potential archaeological sites were found during monitoring of topsoil-stripping on the Celbridge Interchange, from April to December 2001 (Licence no. 01E0306). Most were resolved through subsequent excavation. The scheme was approximately 4km in length and ran from Celbridge to Leixlip through gently undulating land with a mixture of arable, pasture and woodland. The southern part of the scheme runs through an area heavily influenced by 18th-century landscape design, with avenues, woodland and tree-lined field boundaries centred on the early 18th-century house at Castletown. This site (Site 16) was divided into three phases: Phase 1, the earliest, consisted of all features which cut the natural subsoil. Phase 2 was the large northerly orientated ditch, and Phase 3 was the final phase of ploughing. Phases 1 and 2 may be contemporary but as explained below, have been dealt with separately. Nine features were identified in Phase 1, mostly concentrated in the north-western area of the site. In the north-western sector there was a hearth feature, two shallow post-holes, two pits and a possible post-hole. In the south-eastern quadrant there was a linear cut and an oval pit. In the south-western corner was an oval cut. These features suggest a habitation site of some kind. There was, however, no obvious pattern to the post-holes nor enough of them to suggest a structure. The two post- or stake-holes close to the hearth may have been associated with it. Burnt and unburnt bone was found in the pit close to the hearth. It may have been a rubbish-pit. It was truncated on its southern side by a plough-furrow. Two pits, 0.35m apart, were found in the southern area of the site. Burnt and unburnt bone was found in the fills of one of them. Burnt bone and a sherd of medieval pottery were found in pit C23. The sherd was the only artefact from this phase and therefore suggests a medieval terminus post quem for it. Phase 2 is represented by a large northerly orientated ditch which cut through the entire site. It did not truncate any of the features described in Phase 1 so may be contemporary with them. It had a C-shaped profile in the south and a rounded V-shaped profile in the north. The fills varied from north to south. The fills of the ditch produced animal bone, cremated bone and two fragments of human skull. The skull fragments were found at the base of the ditch, along with 23 cattle-sized vertebrae fragments. Other cattle parts included a molar, a horn core, a humerus, a metacarpal and a metatarsal. These disarticulated bones were probably dumped into the ditch when it was open. The only artefact found in the ditch fills was an iron blade. Five fragments of cremated animal bone were found in the same fill as the blade. This feature seems to have been a boundary ditch. It does not correspond to any ditches marked on the first edition OS 6-inch map so must pre-date the early 19th century. Phase 3 is represented by nine plough-furrows. They ran across the site from east to west and truncated the large ditch and some other features. They varied in width from 0.8m to 0.3m. Several post-medieval artefacts were found in the furrow fills, including pottery sherds, glass, clay pipe fragments and a nail. A flint flake was found in fill C12. Other artefacts were found in the topsoil during cleaning. These included a silver button, nails and two flint flakes. (www.excavations.ie) Compiled by: Gearóid Conroy Date of upload: 10 June 2011

• KD011-055 Excavation - miscellaneous
  Description

  Eighteen potential archaeological sites were found during monitoring of topsoil-stripping on the Celbridge Interchange, from April to December 2001 (Licence no. 01E0306). Most were resolved through subsequent excavation. The scheme was approximately 4km in length and ran from Celbridge to Leixlip through gently undulating land with a mixture of arable, pasture and woodland. The southern part of the scheme runs through an area heavily influenced by 18th-century landscape design, with avenues, woodland and tree-lined field boundaries centred on the early 18th-century house at Castletown. This site (Site 17) lay 15.4m to the south-east of Site 16 (KD011-054----). The area measured 6m by 4m and was visible as two charcoal-rich deposits. The site can be divided into two phases. Phase 1 is represented by a northerly orientated bottle-shaped cut. It was 4m in total length and 1.08m wide in the oval part. The 1.3m southern projection was 0.25m wide. It was dug into the natural subsoil. It had vertical sides in the flue and gradual concave sides in the main oval section. The base was flat. The main, widest, part of the cut had eight fills. Some of these fills partly filled the flue; two were confined to the flue only. The fills were rich in charcoal and ash, and some contained burnt clay and bone. At first it was thought that this feature might have been a corn-drying kiln. A portion of one of the charcoal-rich fills was sieved in an attempt to identify some charred seed remains. None were found. All the identified fragments of bone found in the fills were of juvenile pig and had been burned at 300-600ºC. Because of the ash deposits and cremated bone fragments it can be suggested that this feature was a pig-roasting pit. It is not possible to determine whether it is contemporary with the features on Site 16. Phase 2 is represented by an east-west-running furrow, probably contemporary with the furrows on Site 16 to the north. (www.excavations.ie) Compiled by: Gearóid Conroy Date of upload: 10 June 2011

  Description

  Eighteen potential archaeological sites were found during monitoring of topsoil-stripping on the Celbridge Interchange, from April to December 2001 (Licence no. 01E0306). Most were resolved through subsequent excavation. The scheme was approximately 4km in length and ran from Celbridge to Leixlip through gently undulating land with a mixture of arable, pasture and woodland. The southern part of the scheme runs through an area heavily influenced by 18th-century landscape design, with avenues, woodland and tree-lined field boundaries centred on the early 18th-century house at Castletown. This site (Site 18) comprised a stone-lined kiln, a possible wall and a possible drain. There was no direct stratigraphic relationship between the kiln and the wall. Evidence was found for two phases of kiln use. The first phase was found under the stone phase (Phase 2) and was sealed off from it by a deposit into which the structural stones of Phase 2 were set. A charcoal deposit at the base of the kiln cut represented this phase. The second phase of the kiln was of stone set in a keyhole-shaped cut. The single course of roughly hewn stones was set along the circumference of the bowl in C23, with a 0.8m gap at the flue. The largest stones were placed at the neck of the flue. The cut was orientated in a north-westerly direction. It was 2m wide in the bowl area and 0.8m in the flue section. Its sides were almost vertical while the flue sloped gently down into the bowl. C18 was a charcoal deposit found at the base of the kiln. It has been sampled for cereal remains and other environmental evidence. C6 represents the destruction phase of the kiln and was confined to within the kiln. It contained some stones that might originally have been part of the kiln structure. Burnt and unburnt animal bone, a sherd of medieval pottery and post-medieval pottery were found in it. A wall survived to the north-west of the kiln as a single course, one stone wide for most of its length but two stones wide at its north-eastern end. The destruction phase of this feature is represented by a deposit of loose stone found along the south-eastern edge of the surviving section. The wall may have functioned as a windbreak for the kiln. It is not possible to establish by artefacts the date of the kiln's use since none were found associated with those phases. Since post-medieval pottery sherds were found in the destruction level it could be suggested that it had a post-medieval destruction date. The presence of two sherds of medieval pottery on site indicates medieval activity in the vicinity or possibly a date for use of the kiln.
