• DU023-023 Historic town
  Description

  Dalkey is a medieval manorial centre with borough status from the middle of the thirteenth century (McNeill 1950, 113). In 1326 there were 39 burgesses (ibid 195). It was the best deep port close to Dublin and was in use during the thirteenth century (Sweetman 1875-86, I, No. 2671). In the fourteenth century it became a supply centre and depot for ferrying men and goods to assist Edward the I's campaign in Scotland and Wales (D'Alton 1838, 445). In the fifteenth and sixteenth centuries it was a bastion of the Pale and the weekly market and fair were held there (McNeill 1950, 247). The town plan is linear and is based on a single street i.e. Castle Street with a number of laneways which run perpendicular to the street. The market place was held in Castle Street, which expands towards its eastern end. Monitoring of groundworks in 2003 at 46-47 Castle Street exposed medieval deposits containing animal, bird and fish bones. Numerous sherds of medieval pottery, mostly of local manufacture were recovered (McQuade 2006, 114-5). Compiled by: Geraldine Stout and Padraig Clancy  Revised uploaded on: 22 May 2018

• DU023-023016 Town defences
  Description

  The S defences of the medieval borough of Dalkey are defined by a dense hedge line that runs along a linear escarpment in the slope (H 2m) and forms the S limit of the burgage plots that fronts onto Castle Street in Dalkey Village. A possible associated bank (Wth 3m, H 2m) has been identified behind Bay View House and Melrose. It is bounded by Cunningham Road to the S and Dalkey Avenue to the W. The W line of defence of Dalkey may be represented by a long linear boundary running S from Barnhill Road, to the corner of Green Banks House (326441/226915). The E end of Castle Street probably marks the limit of the medieval town on the E side. The N limit has not been identified. Excavations in 1996 at 59 Castle Street uncovered a ditch directly below the partition wall between houses No. 7 and No. 8 which may represent the S extent of a burgage plot (96E0297; Murtagh, 1997, 18). In 1482 the bailiff of Dalkey was granted the right to levy customs on all goods and merchandise coming into Dalkey and to use the money for murgage and pavage (McNeill 1950, 247).

An incised line extends down the centre of the slab, through the cupmark and on each side of this line are six diagonal lines, forming a rough herringbone pattern (Ó hÉailidhe, 1982, 139-40, Fig. 53b; Swords, K. ed. 2009, 88-9).

• DU023-064001 Habitation site
  Description

  A habitation site excavated at 62 Castle Street by John Kavanagh under licence 02E1871. The earliest phase of activity identified on the site was characterised by a series of features associated with a medieval burgage plot. The plot was defined by a ditch and drain along the E boundary of the site. Numerous domestic rubbish pits were found within the area of the burgage plot. Several post-holes, stake-holes and hearths, located along the S edge of a metalled surface, suggested a habitation area at the N end of the site. The pottery assemblage recovered from these features would indicate a mid-12th- to late 14th-century date. Other artefacts included a bone spindle whorl, and iron knife, fragments of rotary querns and several fragments of green glazed floor tiles. A substantial stone building (DU023-064001-) was constructed directly over the medieval habitation area. The building occupied the NW corner of the site and extended out under Dalkey Avenue to the W.

• DU023-064002 Building
  Description

  A stone building excavated at 62 Castle Street by John Kavanagh under licence 02E1871. The building occupied the NW corner of the site and extended out under Dalkey Avenue to the W. The foundation rubble of the E wall and the lowest course of stone of the N wall survived. A very small portion of the S wall was visible in the E facing section of the site. No entrance was found. To facilitate the construction of the E wall a large linear foundation trench, 14m in length and 2.25m wide, was excavated. The poorly preserved east wall was 14m in length and consisted of irregularly shaped granite stones, laid down in a rather haphazard fashion. The foundations had a maximum width of 1.6m and height of 0.42m. The N wall had a length of 4.5m and extended into the W baulk. The surviving stone course had a width of 1.1m resting on a foundation that was 1.6m wide. The N end of the interior had to be artificially raised to level the surface. A layer of rough cobbling was laid down over 0.35m of redeposited clay. Much of the cobbling was in very poor condition but small areas had remained in situ. Historical and cartographic sources indicated that the building was in ruins by the middle of the 18th century. The site stratigraphy suggested that the building may have been in ruins by the 17th century. From at least the 17th century onwards, silt, sands and gravels began to accumulate in the north-east corner of the site. A sherd of 17th-century Frechen pottery was recovered from the lower layer of sands and silts. Compiled by: Geraldine Stout and Padraig Clancy Revised upload on: 7 July 2018

• DU023-070 House - 16th/17th century
  Description

  Situated on the S side of Barnhill Road, part of a multi-period residence named Dalkey Lodge on the First OS 6-inch edition maps, set with in gardens as a detached house. The earlier house, a rectangular, 2-storey rendered masonry structure is placed with its long axis facing the street along an ENE-WSW axis. The adjoining 18th century house, following the same alignment is set back a little from the earlier structure. The earlier structure consists of rectangular 2-storey rendered masonry house, 9.4m E-W and 6.7m N-S externally, with a flat-headed entrance at ground floor level and a flat-headed but internally splayed window embrasure at first-floor level. On the south front there are two large flat-headed openings which are not original at ground and first floor level. According to the deeds this house was first constructed in 1658 just off the Barnhill Road (pers. comm. Marguerite Ryan). The later structure is a five bay double pile house with steeply pitched roof, expressed chimneys and centrally placed Gibbs doorway. In the later 18th century the house was again extended to the S.
