Built by one Melughlin O’Kelly, this rectangular tower house measures 7.8 metres long by 7.3 metres wide and sits atop an artificial mound that stretches 55 metres north to south and 24 metres east to west, raised about 1.5 metres above the surrounding wetlands where a stream meanders southwest.

The castle’s current state tells a story of both resilience and ruin. Whilst the north wall and most of the eastern and western walls survive to their original height, the south wall has vanished entirely, leaving only foundation stones. The original entrance likely stood in this missing south wall or possibly in the west wall, where a large breach now gapes; remnants of a spiral staircase at the broken edge suggest this was once a major access point. Another doorway, now robbed of its stones but flanked by two gun loops, can be traced in the north wall. Inside, the positions of the wooden floors are marked by corbels and beam slots, whilst an intramural passage runs through the west wall on the second floor.

The tower’s domestic arrangements reveal themselves through a series of fireplaces scattered throughout the structure: three in the east wall on the first, second, and third floors, with those on the first and third floors rather awkwardly blocking what were once windows; an ogee-headed single light and a two-light transom and mullioned window respectively. A fourth fireplace appears in the west wall on the fourth floor. The roofline shows interesting architectural details, with the north gable rising inside the parapet wall alongside a chimney stack on the west wall, whilst the eastern chimney rises directly from the parapet itself. A decorative string course runs around the entire structure, and corbels that once supported defensive machicolations crown each wall. Most of the remaining windows have been robbed out over the centuries and may have been later additions anyway; one third-floor window in the north wall appears to block an earlier, possibly two-light rectangular opening.
