What remains today are two distinct structures: the fragmentary ruins of a rectangular tower and, slightly downhill to the south, the ivy-clad walls of a later building. The site has suffered from quarrying and is now largely overgrown, lending it an atmospheric, if somewhat neglected, appearance.

The main tower, measuring roughly 5.5 metres east to west and 3.6 metres north to south internally, reveals intriguing architectural details despite its ruinous state. Most of the eastern and western walls at ground level have vanished, but the southern wall contains two arched recesses that obscure a blocked slit window. A stairwell entrance once existed at the eastern end of the north wall, with stairs rising straight through the wall to the northwest corner. The first floor features a pointed barrel vault running east to west, though it’s in poor structural condition, whilst the second floor retains only the lower courses of its walls with traces of window openings. About twenty metres south, a second building’s eastern wall stands to its full three-storey height plus attic, complete with a second-floor fireplace and chimney stack, though ivy obscures most of its features.

The castle’s history stretches back to the early 13th century, likely built by Philip de Prendergast after he received these lands in 1207. Through marriage, ownership passed to the Cogans and by the late 14th century to the Fitzgeralds, who held it until its dramatic capture in 1568 when Lord Deputy Sidney took the fortress from James Fitzmaurice “after an obstinate resistance.” Whilst the site certainly dates to the 13th century, the visible remains tell a more complex story; the tower appears to have been rebuilt, possibly in the 16th century, whilst the second building likely dates to either just before the English takeover in the late 16th century or the early 17th century.
