A rath is a roughly circular earthen enclosure, typically built during the early medieval period as a farmstead boundary, and souterrains, stone-lined underground passages or chambers associated with such settlements, turn up within them across Ireland with reasonable regularity. What makes this one unusual is the degree to which it has retreated from the archaeological record entirely, surviving only as local knowledge passed from a landowner rather than as any measurable feature in the ground.

The sole account of the feature describes a cavity beneath a rock at the centre of the rath. No structural remains are visible at the surface, and the classification of the site as a souterrain rests on that single reported observation rather than on excavation or survey. The rath itself is recorded separately, so the enclosure is established; the underground element, if it exists, remains unverified. This is not unusual for souterrains in heavily farmed landscapes, where collapse, infilling, and centuries of ploughing can erase any surface trace while leaving a void intact below.
