The structure belongs to the court tomb tradition, a type of megalithic monument built in Ireland from around 4000 BC, typically characterised by an open forecourt leading into a roofed gallery where the dead were placed. This particular example has lost much of its surrounding fabric, but what remains is precise enough to read clearly, a roughly five-metre gallery, just one and a half metres wide, oriented east-north-east to west-south-west across the valley slope.

At the eastern end, two entrance jambs still stand in good condition. Moving inward, the gallery is divided into two chambers by a high sill stone, a threshold between spaces that would once have held the remains of the community's dead. The dividing sill is flanked by imbricated sidestones, meaning stones laid in an overlapping sequence, like slates on a roof, which act as jambs to define the boundary between the two chambers. Over the western portion of the inner eastern chamber, a large roofstone survives in place, giving a sense of the enclosed, deliberate architecture that the original builders intended. Faint traces of the covering mound that would once have enveloped the whole structure are still visible immediately to the north of the gallery. The tomb is recorded and discussed in the landmark survey of Irish megalithic monuments compiled by Ruaidhrí de Valera and Seán Ó Nualláin, published in 1972, which remains a foundational reference for this class of monument across the western counties.
