The Ordnance Survey mapmakers of 1841 to 1842 recorded it as "Kyle Burial Ground for Children", a designation that places it within a quietly significant category of Irish sacred geography. These sites, known in Irish as cillíní or cilléiní, were used for the burial of unbaptised infants and others considered ineligible for consecrated ground, children who existed in a theological grey area and so were laid to rest in places apart, often ancient enclosures whose origins predated Christianity entirely.

By the time the site was mapped again in 1939, the name had disappeared, leaving only the outline of a circular enclosure. What survives today is a well-defined earthen bank forming a near-complete ring around an interior space roughly 27 metres across from north to south. The bank itself behaves asymmetrically: the outer face drops steeply from the crest, while the inner face slopes down more gently, giving the interior a sheltered, bowl-like quality. Three gaps interrupt the circuit, a narrow one to the west measuring around 2 metres, a wider break to the east at about 4 metres, and the largest opening to the south-southwest at 8 metres. Whether these represent original entrances, later agricultural breaks, or something else is not recorded. The external bank stands roughly 1.5 metres tall, and the enclosure as a whole measures 30 metres in external diameter, dimensions that place it comfortably within the range of early medieval ringfort-type enclosures, though here the association is with burial rather than habitation.
