Local knowledge insists it exists, tucked within the south-eastern quadrant of the enclosure's interior, but no surface trace of it remains visible. It was blocked up, pragmatically and apparently without ceremony, to stop cattle from dropping in. That single act of rural problem-solving has left the feature in a peculiar state: present in memory, absent from view, neither confirmed nor disproved.

The earthwork surrounding it is a rath, a type of circular or near-circular enclosure defined by a bank and sometimes a ditch, typically associated with early medieval settlement in Ireland. This one measures roughly 39.6 metres north-north-west to south-south-east and 37.6 metres east to west, with a bank still traceable at the north and south and a scarp defining the circuit elsewhere. It sits in grassland on a ridge, and while it survives in fair condition, quarrying has bitten into it at the south-west and the north. A possible original entrance lies at the south. What local tradition calls the cave is most likely a souterrain, an underground stone-lined passage or chamber that early medieval communities built beneath or beside their settlements, used variously for storage, refuge, or both. This one, if it is a souterrain, is unexcavated and effectively sealed.

The combination is quietly odd: a monument that has endured well enough to be recorded and measured, sitting around a feature that exists only as hearsay and as a hazard once deemed serious enough to block. The quarrying at its edges is the more visible damage, but it is the hidden, stoppered cavity inside that gives the site its particular character.
