This imposing rectangular tower house, measuring 14.5 metres north to south and 11.1 metres east to west, once stood six storeys tall, complete with barrel-vaulted lofts and an attic space beneath its peaked roof. Though time has claimed much of the structure, the north and east walls remain intact, offering visitors a glimpse into the sophisticated defensive architecture of medieval Ireland, from the cut-stone quoins and base-batter to the rather unglamorous but practical garderobe chute that exits at the base of the northern wall.

The castle's interior reveals the complexity of life within these fortified walls. Entry was once gained through a now-destroyed doorway on the south side, possibly secured by a yett (a type of hinged iron gate), leading to a lobby that branched into multiple directions. A newel staircase at the southeast corner, though now destroyed, once spiralled upward to connect all six floors. Each level served its purpose: the ground floor with its embrasures for defence, the upper chambers with their window seats and mural chambers carved into the thick walls, and the distinctive barrel-vaulted lofts that provided additional storage or living space. The remnants of a wall-walk and lookout post at the southeast angle remind us that this was as much a watchtower as it was a home.

The castle's documented history begins in 1640 when it was already "out of repair" and owned by Lord John Power of Curraghmore. It later passed to James Wall of Coolnamuck in 1697, before entering the Morris family of Waterford through marriage at the close of the 18th century. The property was eventually sold off during the Encumbered Estates sales of 1850, a common fate for many Irish estates during that turbulent period. Surrounding the tower, visitors can still trace the defensive fosse (a dry moat) carved around the rock outcrop's base, and the remains of a bawn wall that once enclosed a courtyard measuring roughly 30 by 28 metres. Historical records mention two towers associated with this bawn, though only fragments of one survive west of the main tower house, along with foundations of what are likely more recent domestic buildings within the enclosed space.
