Castle Lough (in Ruins)

On a small limestone island (50m x 20m), now attached to the E shore of Castlelough Bay in Lough Leane by a narrow causeway (L 80m; Wth 10m). The fragmentary ivy-clad remains of a tower (max. H c. 6m) stand at the NE corner of the island. It is built of random rubble bonded by a lime mortar and stands directly on the bedrock. It consists of a rectangular block (8.9m N-S; 7.3m E-W) conjoined on its W side to a larger rectangular block (6.9m E-W; min. 10m N-S). The latter section was modified in the 19th century to create a viewing platform though these alterations are now largely ruinous. The E block contains a rectangular chamber (3.3m E-W; 2.6m N-S) whose SE corner is missing. In the thickness of its N wall are two vertical shafts which must once have served garderobes at a higher level; on the exterior N face is a wide arched opening which is probably associated with these shafts. At the N end of the W block is a chamber (3.8m E-W; 1.65m N-S) covered by a wicker-centred vault which has collapsed. The W half of this room's S wall has fallen but was probably the position of a doorway giving access to a larger room (4.2m E-W; min. 6m N-S) to the S. This latter room was covered by a wicker-centred vault, now almost entirely fallen. The E wall of this room does not survive though it extended at least 3.3m beyond the E block. The N wall of the W block is carried forward c. 1m beyond the line of the E block. Castlelough Castle (or Poolcastle) is now very fragmentary but was once a substantial tower house erected by the Mac Carthy More in the 15th/16th century (Barrington 1976, 204-5). The castle was reduced to its present state when razed by Parliamentary forces in 1652 (Anon. 1913, 83).

Built in the 15th century, Castle Lough was constructed by the Fitzgerald Gerald dynasty, who were prominent Anglo-Irish lords in the region. It is remembered as a strategic defensive site in the Kingdom of Desmond, reflecting the power struggles and territorial control during the late medieval period in Ireland.
