What is recorded here
Kilcolgan Castle is a ruined bawn in County Offaly where two strange corner towers still stand inside a square wall. The towers are circular within but angular without, a shape that defies easy drawing or belief. A date stone marked 1649 above the lost entrance, and a machicolation still guards the memory of the house destroyed for rubble in the 1950s. What remains is not a complete castle but a sharp geometric puzzle set in open countryside, waiting to be seen plainly.
Located on a slight rise in undulating countryside. Only the square bawn (75m E-W; 70m N-S; wall T 1m) with its SE and SW corner towers survive (ext. diam. 8.1m; wall T 0.85m), originally there were four towers. These towers are curious in their construction in that their interior is perfectly circular while they each have an external angle on their side facing away from the bawn. The towers were originally three storeys high with a doorway to each level accessed from an external wooden stairs inside the bawn. Fireplace at first floor level of tower, two centred door with punch dressed jambs and drafted margins. The other doors are all destroyed. At ground floor level there are two small rectangular windows one flanking either side of the destroyed doorway. The S wall of the bawn has a machicolation and rectangular chimney stack at first floor level, which may be the only surviving remains of the destroyed fortified house (OF015-011001-). The machicolation may have protected an entrance to the house. The original entrance to the bawn was at the E end of the N wall which is now destroyed. Above the original entrance was a date stone 1649 (Davies 1942; JRSAI vol. 13, 1874-5, 163) now removed. The fortified house was destroyed in the 1950's by the ESB for rubble to build the nearby power station. Photograph of castle in the architectural archive shows the L-plan fortified house two storeys high with crenellated wall walk, Jacobean chimney stacks with transomed and mullioned windows. Mac Coghlan castle which was visited by Rinuccini in 1648 on his way from Kilkenny to Galway (JKAS 1958, 348-58). (Cooke 1875, 342; O' Flanagan 1933, vol. 1, 85)

Built by the Blake family in the 15th or 16th century, Kilcolgan Castle is remembered as a significant example of a bawn-style defensive structure in the region, reflecting the need for local strongholds during a period of political and social instability.
