What remains today is primarily the western wall of a once-imposing three-storey tower with an attic, stretching approximately 11.5 metres and still topped by its original chimney. The southern wall partially survives too, extending about 6.5 metres with a later buttress added for support at its eastern end, whilst farm buildings have since been constructed against both the interior and exterior of these ancient walls.

The castle’s defensive and domestic features tell the story of its dual purpose as both fortress and home. A garderobe tower projects from the northwest corner, its solid masonry construction pierced by a chute and outlet at first-floor level, though the vault above has long since collapsed. The western wall reveals blocked windows at various levels; a central window with partial hood moulding at the first floor, another at the second floor’s southern end, and a now-blocked central fireplace at the third floor. Particularly interesting are the remains of a mural passage at the first floor’s northern end, lit by two narrow slit windows and containing a garderobe, whilst traces of window embrasures flank the third-floor chimney breast.

The castle’s military adaptations are evident in the surviving wall-walk at the western end of the south wall, complete with projecting drip-stones and two gun loops in the parapet walls; features that reflect the changing nature of warfare in early modern Ireland. As the seat of the Wall family, the castle met its demise in 1642 when it was captured and burned during the Confederate Wars. The Down Survey maps of 1655-6 show the castle still standing, with a mill located close by to the west-northwest, suggesting the site retained some economic importance even after its destruction.
