This rectangular structure, measuring roughly 10 metres north to south and 8.3 metres east to west, rises three storeys high beneath a barrel vault. The castle appears on the Down Survey maps of 1655-6 and was recorded as belonging to Lord Power of Curraghmore in 1640, placing it firmly within the turbulent period of 17th-century Irish history.

The castle’s defensive features reveal the paranoia and practicality of medieval Irish architecture. Entry is gained through a finely dressed pointed doorway on the west wall, complete with a yett (iron gate), leading into a lobby overlooked by a murder hole operated from the second floor. The ground floor chamber, accessed through another pointed doorway with a hanging-eye, features double-splay loops in the north and south walls for defence. A cleverly designed mural staircase winds through the west wall, protected at various points by both musket loops and another murder hole, demonstrating the builders’ determination to make any forced entry as hazardous as possible.

The upper floors show signs of more comfortable living arrangements alongside the defensive elements. The first floor boasts a large ogee-headed window and fireplace in the north wall, with additional windows in the east wall and a garderobe tucked into the southeast corner. Above this, a loft space sits beneath the barrel vault, likely accessed by wooden stairs that have long since disappeared. This level also featured two windows in the east wall and another garderobe, though its entrance is now blocked. While nothing remains above the vault today, the castle’s surviving features paint a vivid picture of a structure built to balance the demands of defence with the necessities of daily life in medieval Ireland.
