  Description

  In undulating pasture, on a ridge at the edge of Castledargan demesne and immediately N of the road. A circular area (int. diam. 31m) enclosed by an earthen bank (Wth 8.9m; int. H 1m; ext. H 1m), truncated at S by the road. A field boundary with a contiguous drain skirts the enclosure NW-E. A trench (Wth 2.4m) which cuts through the bank at NW drains water off the boggy interior to an outer drain. According to local information, prior to the cutting of this trench the interior held water to a much greater depth (M. A. Timoney 2000a, 18). Beech trees grow along the perimeter of the enclosure.

• SL021-045001 Castle - tower house
  Description

  In pasture, on top of a sheer cliff, overlooking Lough Dargan immediately to its N. The remains of a castle built in 1422 by Conor Mac Donagh (Timoney and O'Brien 2000) now survives in two sections, 25m apart. Both are built of uncoursed limestone rubble bonded with a lime mortar. The E block consists of a SE corner (8.85m E-W; 3.5m N-S; T 2.1m) now standing to two storeys but originally higher. At ground-floor level, where the wall breaks off, part of a doorway survives. This gives access to mural stairs, lit by a series of slit windows, that rise to the SE corner and then continue through the E wall to first-floor level where a door, now fragmentary, gave access to a first-floor chamber. There is a large ruined window embrasure in the S wall. The ground-floor chamber was covered by a rounded wicker-centred vault but only the springing courses of this now survive, along the S wall. There are four blocks of fallen masonry, parts of a vault, lying on the ground in the vicinity of the E block. The W block also stands to two storeys, but was originally higher, and only a N-S length of walling survives (L 5.2m; T 2m). At ground level is an angled passageway, with a lintelled door. At the S end of the passage is the corner of a chamber covered by a rounded wicker-centred vault. At first-floor level there is a short right-angled return on the W face of the wall. A curved scarp, partially rock outcrop and partially stone facing, arcs between the two blocks on their S side. This is probably the footings of a bawn wall (SL021-045004-); the W block is likely to be a mural tower connected to the bawn wall, whereas the E block is probably the remains of the main tower. Immediately S of the castle are the ruins of a number of 18th/19th-century buildings (SL021-045002-, SL021-045003-) and a walled garden(s), that were still in use in the 1830s (pers. comm. M. A. Timoney). The site continued to be part of the estate of the nearby mid-18th-century Castledargan House.

• SL021-109001 Country house
  Description

  Listed in both the SMR (1989) and RMP (1995) and classified 'Castle Possible' and 'Castle Possible Site' respectively. It had originally been classified as a possible castle because, according to Martin Timoney (pers. comm. SMR (1989) file), there was the 'stump of old tower behind house'. This tower was not located according to the SMR (1989) file. According to Timoney (unpublished archaeological assessment report for Castledargan Golf Course, 2000, 12) the above information was given by a local in the mid-1970s and that Martin Timoney had not seen the tower himself. In his report he describes the above as 'an old water pump' with a walled garden curving around it which could have been 'interpreted as being a tower'. In relation to the Country House, O'Brien (2000, 6) states in his report that, there is no documentary evidence relating to a building date. However in the light of a possible mid-1700s date suggested by architect Dr. F. O'Dwyer (Timoney c. 2000, 13), O'Brien (2000, 6) states that because of 'the improving family circumstances … and the presence of more that one household in the 1949 Elphin Census, the building of Castledargan House in the mid-1700s would not be and unreasonable supposition.' Martin Timoney (phonecall July 2003) adds that three large beams of worked oak with mortice holes and dowels were found in the house, reused as lintels. The house is dated to c. 1750 with much rebuilding in the 1850s. Compiled by Archaeological Survey Unit, UCC Date of upload: 11 January 2012

• SL021-109002 Designed landscape - folly
  Description

  Not included in the SMR (1989). Listed in the RMP (1995) and classified 'Church'. This folly is incorporated into the SSE wall of an enclosed orchard immediately to E of Castledargan House (SL021-109001-). The avenue to the house is located on the SE side of the wall. An intervening border of rhododendron bushes obscures the SE face of the wall. The wall (8.4m NE-SW; H 2.7m) consists of coursed, mortared stone. A round-arched doorway with cut-stone surround is centrally placed in the wall. To E of the door is a round arched window with a cut-stone surround. Both the door and window openings have been carefully blocked up with drystone walling. At the NE end of the wall, two coursed stones protrude from the base of the NW face, possibly a remnant of a return wall to NW. This is not a church or any ancient feature but rather a demesne feature or folly in the walled garden of Castledargan (ibid.). This monument is post-1700 AD in date.

• SL021-120 Enclosure
  Description

  In undulating pasture, at the E end of Castledargan Demesne. A subcircular raised area (29m N-S; 28m E-W) defined by a scarp (H 1.4m). The interior is uneven and undulating, possibly due to gravel extraction. An annexe (21m x 9m) defined by a scarp (H 0.5m) lies immediately to W and is separated from the earthwork by a N-S fosse (Wth 1m; D 0.4m). The surface of the annexe is flat and even. (pers. comm. M.
