Beneath deciduous trees, small stones break the surface of an irregular enclosure roughly sixteen metres by fourteen, marking what local knowledge identifies as a cillíneach, a children's burial ground. These sites, found across Ireland, were used for the interment of unbaptised infants, who were excluded from consecrated ground under Catholic doctrine. Liminal by design, they tend to occupy boundary spaces, woodland edges, riverbanks, old ringfort interiors, and their modest surface traces, a scatter of small stones, a slight rise in the earth, can be easy to miss entirely.

The site at Crossterry sits in wooded ground, with deciduous trees growing both around and within the enclosed area. Approximately twenty metres to the east lies a souterrain, an underground stone-lined passage or chamber typically associated with early medieval settlement, used for storage or refuge. The proximity of the two features is not uncommon in the Irish landscape, where different periods of use often layer quietly on top of one another without any single moment of dramatic transition. No excavation or formal survey appears to have disturbed the ground here, and what is known comes from local tradition rather than any systematic investigation.
