Built from roughly coursed limestone blocks, boulders and greywacke, this medieval tower house follows the classic Irish design with projecting towers at opposing corners; one at the northeast housing the spiral staircase, and another at the southwest containing the garderobes. While modern additions have been tacked onto the southeast and southwest corners, along with an external stairway leading to the first floor, the castle’s medieval bones remain clearly visible beneath centuries of alterations.

The original entrance, now broken out, once stood in the east wall just south of the northeast tower, opening into a north-south barrel vault and providing access to the stairwell. The ground floor preserves several double-splayed window openings in the north and west walls, with remnants of another much-altered opening in the south wall. Moving up through the castle, the first floor retains evidence of its domestic function with a fireplace set into the east wall and a chimney flue in the south that runs from the barrel vault to the castle’s top. Though the windows at this level have been broken out over time, the western opening still preserves its stone window seating, whilst the eastern one shows signs of a single-splayed design.

The southwest tower’s garderobe chambers offer a glimpse into medieval sanitation, with the first-floor facilities featuring a chute recessed within a semi-circular niche in the chamber’s northwest angle, all topped by a corbelled roof and lit by plain rectangular openings. The second floor, which once rested on wooden beams supported by stone corbels, preserves window remains in three walls, with stone seating still visible in the western and northern openings. Throughout the castle, several small cubby-holes are tucked into the walls at various levels, whilst the northeast stairwell tower features narrow slit openings framed with plain greywacke jambs, all combining to create a structure that, despite its ruined state and various modifications, remains a compelling example of late medieval Irish defensive architecture.
