The question of whether it represents a collapsed souterrain, an underground stone-lined passage typically built during the early medieval period for storage or refuge, has never been satisfactorily resolved. That ambiguity is, in its own quiet way, the most interesting thing about it.

When a fieldworker visited the site in 1946, the irregular depression was examined and judged to be a relatively modern feature rather than the mouth of a genuine early medieval structure. The cashel within which it sits, a cashel being a dry-stone ringfort enclosure, is recorded separately, and the potential souterrain was identified in relation to that enclosure's interior. Without excavation, the question remains open. A depression that looks ancient may be nothing older than a collapsed farm pit; one that looks insignificant may conceal something far earlier beneath it. This one has been neither confirmed nor dismissed with any finality.
