What remains today is primarily the western wall of this once formidable structure, rising four storeys high alongside fragments of its north and south walls; the eastern wall has long since vanished. The surviving tower measures approximately 9.5 metres north to south and nearly 6 metres east to west, with walls an impressive 1.3 metres thick. A barrel vault still spans the first floor, whilst the upper levels once featured wooden floors supported by substantial corbels projecting from the walls.

The architectural details reveal a sophisticated medieval dwelling despite its ruined state. The original spiral staircase in the southwest corner has been destroyed, and Victorian improvers inserted a dovecote into the northwest angle during the nineteenth century. Above the centre of the western wall at wall-walk level, a machicolation juts out, once allowing defenders to rain projectiles on attackers below. Windows throughout the structure show varied designs: simple flat-headed single lights at ground level give way to more elaborate twin-light windows with ogee and flat-headed designs on the second and third floors. Particularly noteworthy is a single-light round-headed window in the southwest corner, decorated with an interlace ring-headed cross above its external head, and a finely carved head in relief adorning the sill-stone of a first-floor window on the western wall. The punch dressing patterns on a second-floor window at the northwest corner bear striking similarities to sixteenth-century work at the mint in Carlingford, County Louth, and at Coole Castle in County Offaly, suggesting a similar date for these modifications.

Enclosing the tower house, a bawn wall of roughly coursed limestone rubble with a distinctive base batter connects to the southwest and northeast corners of the tower, creating a defensive courtyard measuring approximately 34.6 metres east to west and 47 metres north to south. The wall, 0.82 metres thick, features a round-arched gateway at its southern centre, complete with rebated punch-dressed jambs and a hood-moulding over the arch with decorated terminals; classic elements of Irish defensive architecture. Within this protected space, a nineteenth-century house and outhouse now occupy what would once have been the castle’s working courtyard, adding yet another layer to this site’s long history of occupation and adaptation.
