This is a cillín, the Irish term for an informal burial ground historically used for unbaptised infants and others excluded from consecrated ground under Catholic tradition, including stillborn children, those who died before baptism, and sometimes adults regarded as outside the bounds of the Church. These sites are found across Ireland in their hundreds, often unmarked on road signs and easy to overlook, though their presence in the landscape carries considerable weight.

The enclosure measures roughly eighteen metres by fifteen, a subrectangular plot defined on three sides by drystone field walling, the kind of loosely fitted stonework built without mortar that is common across the west of Ireland. The fourth side, to the east, is formed by the boundary wall of the Athenry-Limerick railway line, which means the burial ground and the railway infrastructure exist in an odd proximity, the living infrastructure of Victorian-era engineering abutting a place of much older, quieter use. Most of the grave-markers lie recumbent, flat against the ground and partially obscured by encroaching vegetation, but in the south-west corner a number of small upright stones survive, set into the earth in the manner typical of these informal memorials, modest and uncarved.

The site is partially overgrown, which is itself characteristic of cilliní across Ireland; without formal maintenance or parish oversight, many have gradually retreated beneath grass and scrub. The upright markers in the south-west sector are worth looking for carefully, as they are easy to miss among the rougher ground cover, but they give the clearest sense of how the space was once actively used and tended.
