It is a subrectangular burial ground, roughly 28 metres across its longest axis and 16 metres wide, bounded on all sides by a low earthen bank. What sets it apart from the ordinary run of rural graveyards is its purpose: according to local tradition, it was used exclusively for the burial of children.

Places of this kind are scattered across Ireland, known in many areas as cillíní, from the Irish word for a small church or oratory. They served as informal burial grounds for those who, under Catholic practice, could not be interred in consecrated ground, most often unbaptised infants. The grief attached to them was generally private, even suppressed, and many such sites passed out of living memory with little formal documentation. This particular enclosure was noted by O'Flanagan in 1927, who recorded the presence of set stones within the interior, marking graves aligned on an east-west axis, the traditional Christian orientation placing the body to face the rising sun. The low bank defining the perimeter is a common feature of these sites, distinguishing the ground as set apart without the elaborate masonry of a formal churchyard.
