Now in a perilous state, this tower house exemplifies the defensive architecture typical of medieval Ireland, with its roughly coursed rubble walls held together by shell and pebble mortar, and massive undressed boulder stones marking its corners. Two angle towers punctuate the building; one at the northwest corner housing the garderobes, and another at the northeast containing the spiral stairwell that once provided access to the upper floors.

Entry to the castle is through a doorway in the north wall, featuring a two-centred arch built from small greywacke slabs. The defensive nature of the structure is immediately apparent, with a murder hole positioned above the entrance and a bar hole in the western jamb for securing the door. Throughout the building, windows vary from large rectangular openings with punch-dressed limestone jambs on the lower floors to narrow defensive slits higher up. The interior reveals practical medieval living arrangements, including fireplaces on the first and second floors supported by corbels projecting from the east wall, and garderobe chambers ingeniously recessed into the corners, complete with chutes and corbelled roofs reaching 2.3 metres in height.

The castle’s upper levels showcase sophisticated medieval engineering, with the wall-walk constructed from large limestone flags that slope outward for drainage, extending slightly beyond the walls below to support the battlements. The angle towers rise two storeys above the main roof level, accessible via stone steps built into the walls following the battlement line. Curiously, the third floor of the main building lacks direct stairwell access, suggesting wooden steps once connected it to the second floor. The southeast and southwest angle towers project inward over the main building’s corners, supported by squinches rising from just below the third-floor ceiling level, whilst the uppermost storey offers barely 1.6 metres of headroom, indicating it may have served as storage or defensive space rather than living quarters.
