This circular tower house, built from roughly coursed limestone rubble, rises four storeys high with a diameter of just over 9 metres. Its thick walls, measuring 2.3 metres across, have weathered centuries since its construction, likely in the late medieval period. The castle’s defensive features are still clearly visible: battlements crown the structure, whilst machicolations project from the wall walk, strategically positioned above the original western entrance and at other key points around the tower. The entrance itself, a pointed doorway, was blocked during the 19th century, though evidence of the castle’s sophisticated defence system remains, including a murder hole that once allowed defenders to attack intruders from above.

The interior reveals a carefully planned living space adapted for both comfort and security. The ground floor chamber, circular in plan, receives light through three windows set into deep embrasures, each flanked by musket loops; a practical reminder of the castle’s defensive role. A spiral staircase tucked into the north wall connects all floors, whilst the first floor, originally supported by wooden beams, features an elegant stone vault overhead. Above this, the second and third floors shift to a square plan, each containing a fireplace in the east wall and generous windows. Two garderobe chambers, essentially medieval lavatories, were built into the eastern wall at different levels, their chutes exiting discreetly at ground level. Traces of internal wall render and several storage niches suggest these upper chambers served as the principal living quarters.

The castle’s history stretches back to at least 1640, when Sir William St. Leger, Lord President of Munster, held the property. By the time of the Civil Survey in 1654;6, it was already described as “an old ruined castle,” suggesting it had seen better days even then. Archaeological evidence hints at darker chapters in its past; 19th century discoveries of skeletons in nearby fields and a helmet found in the vicinity speak to possible conflicts. The site includes remnants of additional structures: traces of a house added to the south face of the tower, possibly in the late 16th or 17th century, and a stone lined well 40 metres to the northwest. Aerial photography has even revealed the ghostly outline of a levelled bawn wall, the defensive enclosure that would have once surrounded and protected this impressive fortification.
