The structure features a distinctive design with towers at both the northeast and northwest corners that rise above the main walls, with the northeast tower containing the stairwell that once provided access to all levels. Evidence on the north wall reveals that another building was once attached to the castle, its roofline still visible in the stonework, whilst the original doorway, positioned east of centre in the same wall, now only retains its western jambs.

The castle’s defensive features are particularly well preserved, offering insights into medieval security measures. Upon entering through the main doorway, visitors would have passed beneath a murder hole; a square opening overhead that allowed defenders to attack intruders from above. The entrance to the stairwell, marked by a finely crafted two-centred arch of punch-dressed limestone, sits just to the east of this main entrance. The ground floor is covered by a barrel vault constructed using wicker centring, whilst the first floor contains a fireplace in the north wall and access to a mural passage leading to both a garderobe and defensive openings. The second floor, which was supported by corbels set into the north and south walls, connected to another garderobe in the west wall’s mural passage.

The castle’s windows tell a story of both defence and comfort; from simple slits and defensive openings to more elaborate features like the decorated first-floor window with hood moulding on the east wall, and the ogee-headed window at third-floor level. An armorial plaque adorns the east wall just below a two-light window, marking the status of the castle’s inhabitants. The third floor, with its notably low clearance of only 1.5 metres, was likely used for storage and accessed by wooden steps from below rather than directly from the stairwell, an arrangement also found at nearby Dunmahon Castle. Though the wall walk that once crowned the structure is no longer accessible, the surviving architecture provides a remarkably complete picture of life in a medieval Irish tower house.
