Only two metres long and narrowing from just over a metre wide at its western end to less than a metre at its eastern, it is a wedge tomb, one of the most common megalithic tomb types in Ireland, built roughly between 2500 and 500 BC. Wedge tombs take their name from this characteristic tapering plan, and most are oriented with their broader, open end facing broadly south-west, towards the setting sun. The example at An Chlochbhuaile follows that pattern precisely.

The structure is modest but intact in its essentials. Three sidestones survive along the northern wall, two along the southern, and a single backstone closes the eastern end. A solitary roofstone sits across the top. What is absent is almost as telling as what remains: there are no indications of a surrounding cairn or mound, which on many wedge tombs would originally have enclosed and defined the chamber. Whether that material was robbed out over the centuries, or whether this tomb was always relatively unelaborated, is unclear. The site sits to the north-east of Douce Mountain in mid Cork, a quiet upland setting that would have placed it at the edge of productive land, which is fairly typical of where these monuments tend to appear. The tomb was recorded by de Valera and Ó Nualláin in 1982, whose systematic survey of Irish megalithic monuments remains a foundational reference for sites like this one.
