The enclosure is roughly circular, measuring approximately 47 metres east to west and 45 metres north to south, and what survives is less a bank than a scarp, rising between half a metre and just over a metre in places. The southern arc has been largely levelled by a pathway that skirts it, and a field boundary cuts across the interior, dividing it almost equally. It is the kind of site that could be walked past without a second thought, were it not for what it is locally remembered as.

The place is known in the area as a children's burial ground, which in Ireland points toward a particular and poignant tradition. Sites of this kind, often called cillíní, were used for the burial of unbaptised infants, who under older Catholic practice were considered ineligible for consecrated ground. The word killeen itself derives from the Irish cillín, a diminutive of cill, meaning church or cell, and it appears frequently in place names associated with early Christian activity or marginal burial practice. What strengthens the case for an ecclesiastical origin here are two associated stones recorded at the site: a pillar stone and a cross-inscribed stone. Upright pillar stones and stones bearing incised crosses are both well attested in early medieval Irish ecclesiastical contexts, sometimes marking boundaries, sometimes graves, sometimes the presence of a founder's cult. References to this site appear in published work by Crawford in 1913 and again in 1926, and by English in 1971, suggesting it has attracted notice for over a century without ever quite settling into a firm interpretation.

The enclosure as it appeared in 1976 already showed signs of gradual erosion, with a section at the western side having been dug away. A field boundary imposed on the interior further complicates any reading of the original layout. The associated stones remain the clearest indicators that this was once a place set deliberately apart, and the persistence of local memory connecting it to children's burial gives it a human weight that the earthwork alone, now so reduced, would not immediately suggest.
