What remains is a wedge tomb, a type of megalithic burial monument built during the late Neolithic and early Bronze Age, typically characterised by a gallery that tapers in height and width from one end to the other. This one is modest even by those standards: a ruined gallery roughly three metres long and one metre wide, covered by three surviving roofstones and oriented along an east-northeast to west-southwest axis.

The structure was recorded and described by Ruaidhrí de Valera and Seán Ó Nualláin in their Survey of the Megalithic Tombs of Ireland, published in 1982. Their account notes that the western end of the southern side has collapsed, and that only two stones remain to represent the outer walling that would once have enclosed the gallery. Perhaps the most intriguing detail is a kink in the northern wall combined with a jamb-like stone at the entrance, features which together suggest that the tomb may once have had some form of portico, a small antechamber or forecourt arrangement at its entrance. Such features are not unusual in wedge tombs elsewhere in Ireland, but here the evidence is fragmentary enough to leave the question open. There are no clear signs of the earthen or cairn mound that would originally have covered the monument, meaning what is visible today is essentially the stripped stone skeleton of a much larger construction.
