Dating likely from the late medieval period, the structure measures 14 metres north to south and 11 metres east to west, with walls a substantial 1.5 metres thick. Though time has claimed much of the building, leaving only the eastern and southern walls standing to their original three storeys, these surviving portions still reveal fascinating details about life in a medieval Irish stronghold.

The tower’s limestone rubble walls, laid in random courses, show evidence of various alterations throughout the centuries. At ground level, three narrow slit windows pierce the south wall, each set within segmental arched embrasures; classic defensive features that allowed defenders to observe and potentially fire upon approaching threats whilst remaining protected. The walls exhibit a slight base batter, a common medieval construction technique that strengthened the structure’s foundation. Notably absent are any signs of internal vaulting or a stone stairwell, suggesting the original floors were wooden, supported within the thickness of the walls themselves.

Later inhabitants made their own mark on the ancient structure, inserting fireplaces to bring some comfort to what must have been a rather austere dwelling. One fireplace was added to the north end of the east wall at ground level, whilst another, now blocked, was installed on the south wall’s first floor. Intriguingly, this later fireplace sits directly in front of an earlier double garderobe chute that exits through the outer face of the wall; a medieval toilet facility that the fireplace builders clearly deemed expendable. A large square window at the eastern end of the south wall’s first floor represents another modification, perhaps added when defence became less critical than natural light. A later building, now also ruined, was eventually constructed at the tower’s southwest angle, testament to the site’s continued occupation long after its military importance had waned.
