The site consists of a raised circular platform measuring approximately 16 metres northwest to southeast and 20 metres northeast to southwest, which likely served as the motte, the defensive mound typical of Norman fortifications. To its north lies what appears to be a bailey, a larger enclosed courtyard area stretching about 27 by 40 metres, where the castle’s everyday activities would have taken place.

The bailey’s boundaries tell a story of strategic medieval planning; its perimeter is defined by natural scarps running from the northwest around to the southwest, whilst a watercourse marks its western and northern edges. The northeastern and eastern sides drop away into the Glenlary ravine, creating a formidable natural defence. A constructed bank encloses the southwestern section, completing the defensive circuit. This clever use of the landscape’s natural features would have made the castle particularly difficult to assault.

The site has been documented on Irish Ordnance Survey maps since 1840, when it was first depicted as a raised circular area defined by a scarp. By the 1897 edition, cartographers had identified it more specifically as a platform with a possible bailey. Today, the monument sits about 140 metres east of another enclosure, and though now covered in trees, aerial imagery from Digital Globe and Google Earth clearly shows the castle’s footprint surviving in the landscape, a testament to the enduring mark left by Ireland’s Norman invaders.
