This rectangular earthwork, measuring approximately 50 metres from northeast to southwest and 39 metres from northwest to southeast, sits on slightly elevated ground surrounded by waterlogged, peaty soil. The site’s strategic position offers commanding views down the valley to the southwest, whilst a natural spring in the northeastern corner would have provided a reliable water source for its former inhabitants.

The fortification consists of three defensive elements: an inner bank standing about 0.7 metres high on the interior side, a water-filled ditch or fosse that’s roughly 8 metres wide and 2 metres deep, and an impressive outer bank that rises to 2 metres in height. These earthworks are best preserved along the southeastern and southwestern sides, though modern intrusions have taken their toll; a track has cut through the northwestern defences, whilst the northeastern outer bank has been incorporated into a field fence alongside the adjacent road.

Within the protected interior, archaeological traces reveal the foundations of several buildings clustered in the southern section, running along the southeastern and southwestern sides of the enclosure. One structure appears notably larger than the others and may represent the remains of the castle itself, first documented on the 1839 Ordnance Survey map. Additional building foundations near the western corner suggest this was once a substantial settlement, likely serving as a fortified residence or bawn during Ireland’s turbulent medieval period.
