A calluragh, sometimes spelled cillín, was a place set aside for the burial of unbaptised infants and others who, by the customs of the time, could not be interred in consecrated ground. This one was in active use until the 19th century, and the interior of the enclosure still reflects that long purpose: the foundations of three huts can be traced within its perimeter, but the rest of the space is given over almost entirely to graves.

About ten metres to the east of the enclosure, a cross-slab stands upright on a cairn of stones. The cairn itself is the feature that gives this site its listed name. Cross-slabs, simple stones incised or shaped with a cross rather than the elaborately carved monuments of later Christian tradition, appear frequently across the early medieval landscape of the Corca Dhuibhne region, the territory that takes in much of the Dingle Peninsula. Their association here with a burial ground used into relatively recent centuries points to a continuity of sacred use that stretches back considerably further than the 19th century. The surrounding valley, sheltered by two of the peninsula's more prominent upland ridges, would have provided a degree of seclusion that suited a site of this kind, set apart from everyday settlement but not entirely remote from it.
