Wedge tombs are among the most numerous megalithic monument types in Ireland, built roughly between 2500 and 2000 BC during the late Neolithic and early Bronze Age. They take their name from their tapering plan, wider and taller at one end, narrowing towards the other, and are typically orientated to face the setting sun in the west or south-west. This one follows that pattern faithfully, its chamber aligned east to west, the wider, open end facing into the afternoon and evening light.

The chamber here measures 2.7 metres in length. At its western end it is 1.4 metres wide, narrowing to 1.15 metres at the eastern end, where a backstone closes off the tomb. The north side of the chamber is formed by a single sidestone; the south side by two. Two roofstones survive, and their condition tells a quiet story of slow geological time. One, measuring roughly 1.45 by 1.4 metres and 0.2 metres thick, still rests in its original position, supported by the backstone, the northern sidestone, and the more easterly of the two southern sidestones. The second roofstone, larger at 2 by 1.55 metres, has shifted southward from where it was originally placed, now overlapping the south-west corner of the first and in doing so concealing some of the stonework beneath it. A scattering of stones embedded in the ground immediately to the west of the chamber may represent the remains of further structural elements, though their precise original arrangement is unclear.
