This limestone rubble tower house, measuring 11 metres east to west and 8.5 metres north to south, was originally four storeys tall but now rises to just three. The thick walls, over two metres wide with a slight outward slope at the base, have partially collapsed; only the south and west walls remain intact, along with a portion of the north wall. The main entrance once stood in the now destroyed east wall, where it provided access to a spiral staircase in the southeast corner that connected all floors except the ground level, which today lies buried under rubble.

The surviving architecture reveals sophisticated medieval design elements typical of late 16th-century construction. The first floor features two elegant ogee-headed windows with hollowed spandrels and carefully dressed stone jambs, set within deep window recesses. A narrow passage built into the western end of the north wall leads to a garderobe in the northwest corner, whilst the second floor contains similar mural passages accessing defensive angle loops at the northwest and southwest corners. Above the second floor, a barrel-vaulted attic space once supported a third floor that has since been lost. The remains of a fireplace with chamfered stone jambs can still be seen in the west wall, offering a glimpse of the castle’s former domestic arrangements.

Connected to the northwest corner of the tower house, remnants of a bawn wall link to a later 17th-century house, which shares architectural similarities with Ulster and Scottish castles of the period. This rectangular gabled building, constructed from the same rough limestone rubble, measures 15 metres by 7.5 metres and features chimney stacks at both gable ends. Of particular interest is a circular bartizan, or turret-like structure, projecting from the northwest corner at first floor level, supported by external corbels and pierced with musket loops for defence. The tower house bears striking resemblance to nearby Coole Castle in both layout and architectural features, suggesting they were constructed around the same time during the late 1500s, with the adjoining gabled house and its distinctive defensive bartizan likely added during the mid-1600s.
