The arrangement is easy to overlook, partly because time and encroaching sod have worked against it, and partly because it no longer announces itself with the clarity of a well-preserved monument. What remains is a roughly rectangular setting of upright slabs, open at the western end, measuring about 3.7 metres along its main axis and 2 metres across. A large recumbent slab on the southern side is partly buried under turf, and two further uprights stand east of the main arrangement, aligned loosely with the rest of the structure.

The monument has been interpreted as the remains of a megalithic tomb, the kind of prehistoric chambered structure, typically built to house the dead during the Neolithic or early Bronze Age, that appears in various forms across Ireland and Atlantic Europe. That interpretation was put forward by Henry in 1957, and it remains the working reading of the site. The details of what survives are specific: three uprights form the northern side, ranging from thirty centimetres to a metre in height; a possible packing stone, used to stabilise an upright during construction, sits just outside the eastern end; and the two external uprights to the east are set one behind the other, echoing the alignment of the southern side. None of this is dramatic in scale, but the spatial logic of the arrangement still reads as deliberate. About 200 metres to the north-east lies the early ecclesiastical site of Kilpeacan, which suggests this ridge carried significance across more than one period of occupation, the prehistoric and the early Christian sitting in quiet proximity on the same high ground.
