This rectangular stone structure, which appears as a ruin on Taylor and Skinner’s 1788 map, now consists mainly of its north wall standing to first floor height. The original building measured about 6.6 metres north to south and 4.9 metres east to west internally, with the ground floor once covered by a barrel vault that has since collapsed.

Despite its ruinous state, several architectural features remain visible, including evidence of a fireplace in the west wall, a window in the south wall, and a projecting garderobe tower at the northwest corner. Adjacent to the south side of the castle, the remnants of a bawn; a defensive courtyard typical of Irish tower houses; can still be traced through its collapsed stone walls, encompassing an area roughly 20 metres by 15 metres. The absence of historical documentation about the castle’s ownership has allowed the Templar association to persist in local memory, though the architectural style points more convincingly to the Fitzgerald family, who held considerable power in medieval Munster.

Adding to the site’s historical intrigue is a granite cross slab that now rests outside the bawn’s eastern wall. This impressive stone, measuring over two metres long, features a ringed cross carved in relief at its centre and was originally located at nearby Knockmaon church. Power noted its presence here in 1918, and it serves as a tangible reminder of the area’s long Christian heritage, predating even the medieval castle itself.
