Local tradition holds that a souterrain runs under the site, one of those narrow stone-lined underground passages that early medieval Irish communities built beneath their settlements, most likely for storage, refuge, or both. The difficulty is that there is no visible surface trace of it whatsoever.

The souterrain is recorded in association with a ringfort, the circular earthwork enclosures that dot the Irish countryside in their thousands and date broadly to the early medieval period, roughly 500 to 1200 AD. Souterrains were a common feature of such settlements, typically hand-built from dry-laid stone and roofed with large lintels, then buried under the ground. In this case, the evidence for one existing at all rests entirely on local oral tradition. No earthwork, no depression, no exposed stonework confirms it on the surface. It is the kind of site that sits in a curious middle ground, neither confirmed nor disproved, kept alive only by the memory of people who knew the land well enough to pass a story about it down through generations.

That a tradition of a tunnel persisted at this particular ringfort is itself worth noting. Oral accounts of underground passages in Ireland are extremely common and often dismissed, but at sites like this one, where the archaeological type is well attested and the conditions for survival are reasonable, such traditions occasionally turn out to have a genuine basis. Whether this one does remains, for now, an open question.
