A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement in Ireland, and used variously for storage, refuge, or as an annex to a nearby farmstead. What makes this particular one quietly curious is that its existence rests entirely on local memory rather than cartographic or excavated record.

The site was noted during research into the archaeology of the Iveragh Peninsula, the broad southwestern finger of Kerry that reaches out into the Atlantic. Despite being catalogued in that survey, no physical details were recorded, no dimensions, no structural description, no confirmed access point. The land in question lies to the west of Bentee mountain, but beyond that, the precise location has not been formally established. It is the kind of entry that points to the gap between what communities carry in their collective knowledge and what archaeology has managed to document and verify.
