The enclosure is D-shaped, roughly 90 metres along its northeast-southwest axis and 75 metres across, with the straight edge running along the southeast. What makes it unusual is not just its age or form, but the quiet local tradition that identifies it as a children's burial ground, a cillín, the kind of unconsecrated plot where unbaptised infants were laid to rest outside the rites of the Church. The difficulty is that no evidence of burial has actually been found here.

The earthwork itself survives as a grass-covered stony bank, its arc running from the southwest around to the northeast, surmounted by a drystone wall. At its widest northern point, the bank measures about 5.6 metres across, though it rises only modestly, roughly half a metre on the interior and slightly less on the exterior. It was recorded on Ordnance Survey six-inch maps in both 1837 and 1929, by which time the enclosed area had long been in use as a farmyard. The enclosure sits towards the bottom of an east-facing slope, a position that might have served drainage or shelter in an earlier, agricultural context, though what function the original builders intended remains unclear. The gap between the folk memory attached to the site and the physical evidence is itself a kind of historical puzzle. Traditions of cillíní clung to older earthworks across Ireland, partly because such places already carried a sense of separateness, of ground that stood slightly apart from ordinary use, and the association may have accumulated here in much the same way.
