The rectangular tower, measuring roughly 8.5 metres north to south and 8 metres east to west, was built from roughly coursed masonry that has endured centuries of Atlantic weather. Today, only fragments hint at its former strength; the southwest corner still displays its well-dressed quoin stones standing 2.5 metres high, whilst the southern wall retains its defensive batter, that characteristic sloped base designed to deflect projectiles and strengthen the structure against siege warfare.

The tower’s basement once featured a barrel vault, though it’s now badly damaged and filled with fallen rubble. In the southwest corner, you can still make out faint traces of what was once a spiral staircase that would have connected the tower’s multiple floors. This wasn’t just a standalone fortification; the tower formed part of a larger defensive complex, positioned at the eastern end of a compact inner bawn measuring 15 by 15 metres. This inner courtyard was itself enclosed within a more substantial outer bawn that stretched 62 metres north to south and 52 metres east to west, complete with a corner tower in the northeast that still stands about 2 metres high.

To the east of these ruins lies a small turlough, one of those peculiar seasonal lakes unique to Ireland’s limestone landscapes, which appear and disappear with the water table. The castle’s strategic position on high, rocky ground above this temporary water feature would have provided both a natural defence and a reliable, if intermittent, water source for its medieval inhabitants.
