This rectangular tower house measures approximately 12.5 metres east to west and 10.35 metres north to south, featuring the characteristic defensive base batter that rises to a maximum height of 2.5 metres. The structure retains its cut stone quoins, those carefully dressed corner stones that provided both strength and a degree of refinement to the building, though these only survive partially to the first floor level.

The castle’s interior reveals several notable architectural features that offer glimpses into its original function and design. At the southwest angle, the remains of a newel staircase can still be traced; this spiral stairway would have provided access between the tower’s multiple floors. The eastern wall preserves evidence of a garderobe chute at first floor level, a medieval toilet system that would have discharged waste outside the castle walls. Interestingly, there’s no evidence that this tower house was ever vaulted, suggesting it may have relied on timber floors throughout its occupation.

This description draws from the Archaeological Inventory of County Waterford, published by the Stationery Office in Dublin in 1999, with subsequent revisions by Michael Moore incorporating more recent archaeological research as of August 2011. The castle remains an intriguing example of the tower houses that once dotted the Irish landscape, built by Anglo Norman and Gaelic lords alike as fortified residences during the late medieval period.
