The monument consists of a circular, flat-topped earthen mound approximately 15 metres in diameter, surrounded by distinctive defensive features that speak to its strategic importance during the Norman period in Ireland.

The mound itself is defined by a steep inner scarp, though the southwestern to western sections show signs of defacement where a modern fence now cuts across the base. A substantial berm, measuring 10 to 12 metres in width, encircles the base of the mound from west through north to east, though its southeastern portion has been interrupted by a later bank and trench that runs from east-northeast to west-southwest. Beyond this, visitors can trace a low but steep outer scarp that extends from the west, around the north to the east, and remains visible from the south-southeast through to the south-southwest.

Atop the mound, the remnants of a rectangular structure mark where the castle’s wooden tower would have once stood, typical of Norman motte constructions throughout Ireland. Whilst no obvious bailey remains, keen observers might notice a semi-circular scarp in the field immediately to the southwest, possibly indicating where this outer defensive courtyard once lay. The site was surveyed by the Archaeological Survey of Ireland, with the monument compiled and documented by Alison McQueen, Vera Rahilly and Caimin O’Brien in September 2019.
