What survives is modest in scale, just 1.75 metres long and a metre wide at its broader end, yet the arrangement is deliberate and legible enough to identify it as part of a wedge tomb, one of Ireland's most distinctive megalithic forms.

Wedge tombs are so called because their chambers taper in both height and width from one end to the other, typically opening to the west and narrowing toward the east. This example follows that pattern: three upright stones form the chamber walls, and a single roofstone covers them, tilting gently downward from west to east. The western end, the wider and more open face, is where the structure would have received the dead during the period when these monuments were built and used, broadly the late Neolithic and into the early Bronze Age. What survives here is most likely the eastern end of the original structure, meaning the fuller monument once extended further, with the grander, open western portion now lost or unaccounted for. The alignment, running east to west, is consistent with what is seen at wedge tombs elsewhere across the west of Ireland, where this tomb type is particularly concentrated.
