What appears on older maps as a "Cave", labelled in Roman script, had vanished from the revised Ordnance Survey edition by 1933, with no mark on the ground to explain where it had gone or why it was removed.

The site was first recorded more formally by McCaffrey in 1952, and by 1956 it was being described as a partially collapsed gallery running to around nine metres in length. A souterrain, to use the archaeological term, is a man-made underground passage or chamber, typically associated with early medieval ringforts and cashels, and often interpreted as a place of refuge or storage. The proximity here to a cashel, a stone-walled early medieval enclosure, sitting immediately to the south on the map, made that interpretation seem reasonable. But when investigators returned in 1971, what they found was rather less compelling: two hollows in the limestone, nothing more. Given the thin soils and exposed bedrock characteristic of the area, the conclusion shifted, and the feature was reclassified as most likely a natural cave. The site has not been conclusively located since, leaving it in that uncomfortable category of places that are recorded without being confirmed, named without being found.
