Souterrains are dry-stone tunnels built during the early medieval period in Ireland, typically used for cool storage, refuge, or both. The idea of a warren of them, branching and interconnecting under a modest field, hints at a site considerably more elaborate than its surface appearance would have suggested.

The enclosure itself was recorded as a cashel, a type of early medieval farmstead enclosed by a circular stone wall, and the landowner who knew it described it simply as a circular heap of stones with a small cave inside. A field club visiting in 1945 noted its presence, along with those subterranean passages. By the time more systematic archaeological attention arrived through Julia Cuppage's 1986 survey of the Corca Dhuibhne region, the site had already been catalogued, though its significance was only partially understood. What finished it off entirely was not neglect or erosion but deliberate clearance: local information recorded that the structure was levelled roughly a decade before the survey was updated, the stones presumably dispersed or reused. The stony debris that remained was itself the main clue pointing to a cashel rather than an earthen ringfort, since cashels were built of unmortared stone rather than raised banks of soil.

Nothing remains to visit now. The site exists only in field notes, in Cuppage's survey, and in the memory of a landowner who once walked around a circular heap of stones and looked into a small cave at its centre, without quite knowing what lay beneath.
