What remains today is primarily the eastern wall of what appears to have been a rectangular fortified structure, stretching approximately 13.4 metres in length and rising to an impressive 4 metres in height. The limestone walls, though missing many of their inner facing stones, still show remnants of the southern and northern walls extending from the main structure. The 1838 Ordnance Survey map recorded this as a rectangular building, though time has reduced it to these weathered fragments.

The most striking feature of these ruins is the series of eight gun loops that pierce the remaining walls; five along the eastern wall and three in the southern section. Each opening follows the same defensive design: a narrow rectangular slit on the exterior, measuring just 25 centimetres high and 10 centimetres wide, which widens dramatically on the interior to about 50 centimetres, allowing defenders a wider field of fire whilst presenting minimal target to attackers. Stepped lintels crown each embrasure, a practical architectural detail that has survived centuries of exposure to the elements.

The absence of any door or window openings suggests this wasn’t a residential structure but rather a defensive bawn, a fortified enclosure that would have protected livestock and provided a first line of defence for a larger castle complex. This interpretation gains weight when compared to the similar gun loop arrangements at Moygara Castle’s much larger bawn elsewhere in the county. Local tradition attributes the construction to the MacDonagh family, who held considerable power in this region during the medieval period, though the exact date of construction remains uncertain.
