This is a children's burial ground, known locally as Lisserglass, and its character is defined by absence as much as presence: a roughly rectangular raised platform, approximately thirteen metres by twelve, edged into the hillside and marked not by headstones in any formal sense, but by small, deliberately set stones placed over individual graves.

Sites like this belong to a broader Irish tradition of burying unbaptised children, and occasionally others excluded from consecrated ground, in liminal places set apart from the parish churchyard. These sites go by various names, including cillín or cilliní (the diminutive of the Irish word for church), and they are found across the island in considerable numbers, often on elevated ground, at field boundaries, or near ancient earthworks. The Lisserglass site was noted by O'Flanagan in 1927, suggesting it was already recognised as a place of significance well before the twentieth century drew it into any formal record. Today, the platform is overgrown with bushes and nettles, which is not unusual for such sites; few were ever maintained in the way a churchyard might be, and the vegetation has a way of quietly reclaiming them.
