What remains today is merely a fragment of what was once a formidable tower house; only the southwest corner survives, with portions of the south wall stretching 5.2 metres and the west wall extending 3.5 metres. Built from roughly coursed limestone rubble that’s been crudely pointed both inside and out, these weathered walls rise approximately 12 metres high, offering a glimpse into medieval defensive architecture typical of the region.

The castle’s interior reveals fascinating construction details that have survived centuries of decay. The ground floor features wall presses and remnants of embrasures on both surviving walls, whilst the first floor contains an L-shaped mural chamber within the south wall. This chamber showcases remarkable wicker centring on its roof, much of which remains intact; a traditional building technique where woven branches formed temporary support for stone vaulting. Natural light would have entered through two loops in the south wall and a rectangular opening in the west wall, though the latter has been altered and widened over time, with only the chamfered head of the original narrow, flat-headed window remaining in place.

Historical records paint a picture of the castle’s gradual decline. The Civil Survey of 1654-6 described it as already demolished, standing alongside six thatched tenements, with Daniel O’Brien listed as the proprietor in 1640. By 1840, more detailed observations noted the structure’s green or grit stone construction, with stones varying from small and shapeless to long quadrangular blocks, most dressed with a hammer. The southwest corner showed signs of deliberate dismantling, with stones removed from the battered base, suggesting the building may have been partially quarried for construction materials elsewhere, a common fate for many abandoned Irish castles.
