Today, the fragmentary ruins tell a story of medieval fortification and domestic life. The main tower’s western wall stretches for 7.65 metres and the southern wall for 5.7 metres, whilst the northern wall survives only in its lower courses and the eastern wall has completely collapsed. The walls narrow as they rise, creating the characteristic defensive profile of Irish tower houses. At the upper levels, only short sections of the south and west walls remain standing.

The tower’s interior reveals fascinating architectural details despite centuries of decay. Projecting corbels once supported the first floor, whilst a fragmentary vault between the first and second floors shows sophisticated construction techniques. Window openings appear at various levels; at the second floor, an intact lintelled window embrasure with a defensive slit light pierces the south wall, whilst the third floor contains window openings with built-in seats in both the west and south walls, though only one side of each embrasure survives. At ground level on the western face, an opening for a garderobe chute indicates the castle’s attention to sanitation, a feature common in medieval tower houses.

Adjoining the tower to the north stands a rectangular structure measuring 8.7 metres north to south and surviving for 6 metres east to west. This addition, built with walls just 1.2 metres thick compared to the tower’s substantial 2.35 metre walls, features the base of mural stairs at its broken eastern end and double-splayed window openings in its western and southern walls. Historical records suggest the castle may have been a Geraldine foundation, though it was later associated with both the Coppinger and Cotter families. By the early 19th century, when the antiquarian Francis Grose depicted it, the castle was already ruinous and considerably reduced in height, its glory days long past but its stones still bearing witness to centuries of Irish history.
