The 1842 Ordnance Survey six-inch map labels it plainly as a Children's Grave Yard, placing it within a modest arc running from the north-east to the south. Such sites, sometimes called cillíní, were used for the burial of unbaptised infants and others excluded from consecrated ground, and they are scattered across Ireland in marginal places, field corners, and old boundaries, often barely distinguishable from the surrounding farmland.

By the time the Ordnance Survey revised its maps in 1905 and again in 1936, the recorded enclosure had grown in outline to a roughly D-shaped form, with a straight side running approximately 57 metres east to west and projecting some 30 metres to the north. The boundary is defined by low earthen banks, the most substantial of which stands about 0.7 metres on its exterior face. Part of this arc also forms a segment of an earlier ecclesiastical enclosure nearby, suggesting the site has a longer sacred history than its use as a children's burial ground alone. Most striking are two bullaun stones associated with the enclosure: one sits on the bank to the north-east, the other on the linear bank to the south. Bullauns are boulders or stones with one or more artificial cup-shaped hollows ground into them, and they are frequently found in early Christian ecclesiastical contexts across Ireland, though their precise original function remains debated. The western end of the southern bank extends a short distance beyond the enclosure, turns north, and fades out before reaching the field boundary, giving the earthworks an unresolved, incomplete quality that only adds to the strangeness of the place.

The site lies partly cut off from the rest of the field by the enclosure itself, creating a corner that the maps consistently identify as burial ground across nearly a century of surveying. There are no headstones, no inscriptions, nothing to mark individual graves.
