Somewhere beneath the ground here, archaeologists believe, a souterrain once existed, one of those dry-stone underground passages or chambers built in early medieval Ireland, typically used for storage or refuge. It has collapsed entirely, leaving no surface trace, and the site exists now only as a question mark on the archaeological record.

The question mark has some intriguing depth to it. When the Kerry Archaeological Survey identified this as a possible souterrain site, they noted it might correspond with an account recorded by the antiquarian John Windele in 1838. Windele had been told of a cave containing bones discovered near the nearby townland feature known as Cnoc na Fola, a name translating roughly as Hill of Blood, which sits close by. Windele himself seems to have taken the bones as potentially significant, though archaeologists now consider it more likely that what he heard about was simply a grave rather than a souterrain at all. So the site sits at the intersection of two uncertainties: a possible underground structure that has left no trace, and a second-hand account of bones from nearly two centuries ago that may or may not describe the same place, and may or may not be what anyone originally supposed.
