The National Monuments Service's description

Situated at the NW end of a 19th-century house and appears to have been considerably altered by the occupiers of the house. The remains of the castle are situated on top of a motte-like earthwork (OF026-005002-) with possible surrounding bawn wall which is visible at E angle. Only the W wall of this tower house (dims. c. 7.5m x 8m) remains with a later door inserted into the W gable. The Tower house survives three storeys high and is built with roughly coursed limestone boulders with slight base batter visible. 19th-century church located on site of medieval church (OF026-004001-) to SW of castle. Fireplace and chimney stack at SW angle with possible curtain tower at E angle of bawn (OF026-005003-). Attacked by the Irish confederate army in 1641 when it was occupied by Lettice, Lady Offaly (Fitzgerald 1918-22, 27-8). According to Leask (1918, 4) ground floor was vaulted. (Cooke 1875, 43: O' Flanagan 1933, vol. 1, 53-6)

Testing was carried out under licence no. 04E0076 as part of the planning schedule for a housing development adjacent to a tower-house (SMR 26:5(01)). A series of trenches were excavated by mechanical digger at the house sites, roadways and ancillary works. No features or finds of archaeological significance were revealed.
