The area measures roughly nine and a half metres east to west and just under six metres wide, unenclosed and untended, with the stones set in the characteristic east-west orientation common to Christian burial practice. It is a quiet, easily overlooked place, and that is rather the point.

Sites like this are known in Irish as cillíní, informal burial grounds used for centuries to inter those who were excluded from consecrated churchyards, most often infants who died before baptism but also, in some periods and places, strangers, suicides, and the unbaptised more broadly. The use of an existing ringfort, a circular earthwork enclosure of early medieval origin typically built as a farmstead or defended homestead, was not unusual. Such ancient enclosures carried an ambiguous sacred quality in the folk imagination, set apart from ordinary agricultural land and associated with an older, pre-Christian world. Placing the unbaptised dead within that boundary gave them a kind of liminal resting place, neither fully inside the Church nor entirely outside its protection. The site at Killagh Beg fits this pattern precisely, tucked into the southern portion of a ringfort and marked only by those small, carefully set blocks of local limestone.
