Local tradition holds that a souterrain once lay within the interior of a rath here, one of those narrow, stone-lined underground passages that early medieval Irish communities used for storage, refuge, or both. No surface trace of it remains visible today, which places it in a particular category of archaeological site: known not through excavation or survey, but through memory.

The rath itself, a roughly circular enclosure about 24 metres across, is in very poor condition. A rath, broadly speaking, is a ringfort defined by an earthen bank and sometimes a ditch, and thousands survive across Ireland in varying states of preservation. This one retains its bank only along the southern to western arc. To the south-east, a natural or worked scarp serves as the boundary instead. The rest has been lost to quarrying, which has eaten into the monument on several sides and accounts for much of what is now missing. Whether the souterrain was disturbed or destroyed during that quarrying activity, or whether it simply lies undetected beneath the surface, is not recorded.
