Castle - unclassified

The National Monuments Service's description

Located on a rise in a low-lying landscape c. 150m from the SE shore of Lough Croan, which is called Loughanabrag on the Strafford map of c. 1636 (Simington 1949, Athlone(2)). The Castle Quarter of Corenegee also known as Lisnaguill, amounting to 154 acres, was owned by Richard Dillon in 1641 and he retained most of it in 1662. He was probably connected with the Dillons of Lough Glynn (RO020-003001-), and he owned over 600 acres elsewhere in Cam parish in 1641 and in 1662 (ibid. 99-102).
This is a rectangular grass-covered platform (dims of top 12.7m E-W; 8.4m N-S; dims of base 16m E-W; 13m N-S) defined by scarps (H 0.3m generally to 0.5m at E), known locally as O'Kelly's Castle (Gannon 1972). Traces of the walls can be identified underfoot at W (Wth c. 1.3m) and E (Wth c. 1m). A medieval limestone head (RO048-001001-) (H 0.17m; Wth 0.12m; T 0.12m), thought locally to have come from this monument, is now in NMI (Rynne 1966-71), and architectural fragments (RO045-240----), including the heads of two ogee-headed windows are incorporated into outbuildings c. 330m to the NE.
