The structure sits precariously close to the cliff edge, with only narrow gaps of two metres to the east and four metres to the west separating it from the drop. The tower features opposing lintelled doorways at the eastern ends of its north and south walls, whilst a single double-splayed window opens through the southern wall. Inside, two tiers of stone corbels and regularly spaced joist holes, positioned about a metre apart, reveal an unusual wooden floor arrangement above ground level.

The tower’s most distinctive feature is its stone roof, which consists of two pointed arches separated from each other and the side walls by a series of overlapping slabs, though only one slab now remains between the easternmost arch and the eastern wall. This architectural style mirrors the roofing found at Dunlough and Dunanore castles elsewhere in Cork. Above this level, the tower has not survived the centuries. Remnants of a curtain wall, measuring 0.95 metres thick, extend westward from the southern end of the tower’s western wall for approximately four metres before reaching the cliff edge.

Historical records identify this as a castle of the Barry Roe clan, as noted by antiquarian Thomas Johnson Westropp in 1914. The site was documented in the Archaeological Inventory of County Cork, Volume 1: West Cork, published in 1992, with subsequent revisions incorporating more recent archaeological research. Today, these ruins offer a glimpse into the defensive architecture employed by medieval Irish clans along Cork’s dramatic coastline.
