Within it, a scatter of set stones marks what lies beneath. This is a cillin, the Irish term for an unconsecrated burial ground where, for centuries, unbaptised infants were interred apart from the main parish graveyard. Catholic doctrine held that children who died before baptism could not be buried in consecrated ground, and so communities quietly maintained these separate spaces, often at field margins, old ringfort banks, or parish boundaries. The practice continued in rural Ireland well into the twentieth century, and cillíní remain among the more quietly affecting features of the Irish landscape.

This particular site sits some nine metres east of a large enclosure, a likely ringfort or settlement feature of earlier date. The burial ground itself measures roughly 13.8 metres north to south and 13.1 metres east to west, its boundary defined by a low wall that has kept the space distinct from the surrounding farmland. A cluster of old houses lies close by to the south-west, a reminder that this ground was once at the edge of a living community, used by families who had no other sanctioned place to put their smallest dead. The name Kilteesk carries the Irish prefix "cill", meaning a church or ecclesiastical enclosure, suggesting the area had religious associations stretching back further than the burial ground itself.
