It measures just over twenty-four metres across internally, and its purpose was recorded plainly in the Ordnance Survey Name Books as a large fort and burial place for children. That double designation, fort and burial ground, points to the layered, often ambiguous nature of such sites. What stands here today is something older and more particular: a killeen, the Irish term for an unconsecrated burial ground used for unbaptised infants and others excluded from churchyard burial. These sites were used well into the nineteenth and even twentieth centuries, occupying a quietly sorrowful corner of rural Irish practice.

The enclosing wall is built in drystone construction, meaning no mortar, relying entirely on the careful placement of coursed slabs flanked on both inner and outer faces by upright stones. Only its lower courses survive, but the wall itself is still well-defined and runs to about 1.85 metres wide. A formal entrance passage, around two metres long and 1.3 metres wide, is marked by slabs set on edge at the south-west. Within the enclosure, the foundations of two circular huts survive. The larger, at the north-north-west, has walls 1.5 metres wide enclosing an area of roughly 5.2 by 4.7 metres; the second, at the north-east, is subcircular with an internal diameter of 4.3 metres and its wall is preserved to about half a metre in height. Whether these huts predate the burial use of the site or were built alongside it is not recorded, but their presence suggests a more complex occupation history than the simple designation of children's ground implies. The burials themselves fill the entire interior. Scattered throughout are small uninscribed upright slabs and quartz blocks, generally no more than thirty centimetres high, arranged loosely in north-south rows. Two groupings stand out: one near the southern wall, delineated by edge-set slabs and covering a roughly rectangular area; a second, near the centre, clustering four taller slabs together in an irregular formation. None of them carry inscriptions. The anonymity is total, and deliberate.
