To an untrained eye it might read as nothing more than field clearance, a few large slabs left where the ground dips. But the arrangement is deliberate, and considerably older than any field boundary nearby. This is a probable wedge tomb, a type of megalithic burial monument built during the late Neolithic and early Bronze Age, typically consisting of a roofed gallery that narrows or "wedges" from one end to the other, often oriented to face the setting sun in the west.

The structure, reported by Michael Lynch, is poorly preserved but legible enough to suggest its original form. Two upright slabs appear to have served as the sidestones of a chamber oriented east to west. The northern stone is the larger of the two, measuring 3.5 metres in length and roughly 0.75 metres in height; the southern stone, about 2.2 metres away, runs to 1.3 metres in length at a similar height. Three recumbent slabs, stones that have fallen or settled flat, complete the visible remains. The largest of these, 1.7 metres long and 0.5 metres wide, now rests across the northern sidestone. About ten metres to the north-east, there are traces of a hut site, suggesting that whatever activity centred on this spot in prehistory was not confined to the tomb alone.
