It measures 3.3 metres long and 2.6 metres wide, its long axis aligned northeast to southwest, and it is propped at its southern end by a smaller boulder set at right angles beneath it. On the western side, a further stone, roughly 2.5 metres in length, may once have served as a sidestone, forming part of what could originally have been a closed or semi-enclosed megalithic structure. A field wall now runs across the monument at its northern end, folding it into the working landscape of the townland in the way that many ancient things in rural Ireland eventually get absorbed.

The arrangement is consistent with the broader family of megalithic tombs found across the west of Ireland, structures in which large capstones are raised on supporting uprights to create a chamber, sometimes for burial, sometimes for purposes less easily recovered at this distance in time. The alignment northeast to southwest is not unusual among prehistoric monuments in the region, and the local tradition of associating the site with a grave, however informally transmitted, is often a reasonable guide to genuine antiquity. The structure sits approximately 50 metres east of a ringfort, a type of circular earthwork enclosure commonly built during the early medieval period, roughly between the fifth and twelfth centuries, typically as a farmstead. The proximity of these two monuments, of quite different periods, is a reminder of how repeatedly the same patches of land attract human attention across millennia.
