That uncertainty is not rhetorical. When the site was visited in 1987, it could not be identified with any confidence, leaving open the question of what exactly the cartographers of 1839 believed they were recording when they marked the word "cave" on the first edition Ordnance Survey six-inch map.

The feature sits at the break between steep upper slopes and more gently worked lower ground on the western side of a small stream valley, a topographical setting that could plausibly shelter either a natural opening in the rock or something altogether more deliberate. The alternative possibility is that it is a souterrain, an artificially constructed underground passage or chamber, typically built during the early medieval period in Ireland as a place of refuge or storage, often associated with a nearby settlement or ringfort. The OS mapping of 1839 simply labels it "cave", which tells us that locals recognised something there at that time, but not what they understood it to be. By the time anyone went looking with a systematic eye, the feature had either collapsed, been obscured by vegetation and soil movement, or was simply too ambiguous to classify. It remains on record as a question rather than an answer.
