A ringfort that once measured roughly forty to forty-five metres in external diameter has been ploughed away, and only in dry weather, when the ground reveals its secrets through differences in soil moisture and crop growth, can the ghost of a smaller inner enclosure, around twenty-five metres across, still be traced. That the site survives at all in memory, if not in earth, owes something to the particular weight of its local reputation: it was known in the area as a raheen.

A raheen, in Irish folk tradition, is typically a small, ringfort-like enclosure understood to be associated with the burial of unbaptised children, sometimes called cilliní. These were infants who died before baptism and were, under older Catholic practice, excluded from consecrated ground. Families often interred them quietly in liminal places, and ringforts, already freighted with supernatural associations as the supposed dwellings of the fairy folk, were among the sites chosen. The Corragh enclosure appears to have carried exactly this kind of meaning. It appears on the 1839 edition of the Ordnance Survey six-inch map, making that the earliest documentary record of its existence, though the earthwork itself would have been far older. It sat towards the lower end of a north-west-facing slope, overlooking a col, with the land dropping away to the north-east and south-west and a hill rising roughly eight hundred metres to the north-west. Around 1975, the physical structure was removed, almost certainly by agricultural clearance.

In dry summers, when soil moisture varies across old disturbed ground, the outline of the enclosure can still appear as a cropmark or parch mark in the field. It is the kind of feature that rewards patient looking from a slight elevation rather than close inspection at ground level.
