The word refers to a children's burial ground, sometimes also called a cillín, one of those quietly sorrowful features of the Irish rural landscape where unbaptised infants were interred outside the boundaries of consecrated ground. Catholic doctrine historically denied such children a formal church burial, and so communities set aside their own informal places, often ancient enclosures or liminal spots at the edges of fields and parishes. This one, known in Irish as Baile na hAbha, carries all the ambiguity and quiet weight that these sites tend to accumulate.

The enclosure measures roughly 21 metres in diameter and is defined by a combination of a low earthen bank and a natural or cut scarp, with the interior sitting slightly raised above the surrounding ground on its downslope side. The bank reaches a maximum height of about 0.8 metres. In the southern sector, the original bank has been replaced by a field wall, though it seems to follow the earlier line of the enclosure closely. A gap of around 5 metres at the south-east is thought to mark the original entrance. Inside, the only clearly identifiable feature is an amorphous mound, and there are scattered quantities of quartz stones across the interior, a material with long-standing associations in Irish folk tradition with burial and protection of the dead. Some stone spreads on the bank may be deliberate, though others could simply be debris from field clearance over the centuries. About 5 metres east of the entrance, there are the remains of a rectangular structure measuring up to 16.2 metres east-west by 9 metres north-south, partially divided into two sections and visible through grass-grown mounds, earthfast stones, and portions of field wall. Its relationship to the calluragh is not established, and it remains unidentified. The site was surveyed and documented as part of J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne region, which catalogued the remarkable density of prehistoric and early Christian remains across the Dingle Peninsula.
