The trouble is, nobody can find it. A field inspection found no surface trace whatsoever, either at the recorded location or anywhere nearby, leaving the site as a kind of archaeological question mark pressed into the landscape.

The sole evidence for anything being here at all is a single handwritten annotation. On a map held in the Archaeology Department at University College Cork, attributed to a Captain D. B. O'Connell, someone has written the word "Cave" at this spot. No further detail accompanies it, and the word itself offers little certainty. The feature could have been a natural cave formation, or it could have been a souterrain proper, a man-made construction. The distinction matters, but without further evidence, it cannot be resolved. Complicating things further, the land in this area has been significantly reclaimed over the years, and many of the field boundaries that appeared on the old Ordnance Survey six-inch maps have since been removed. Whatever O'Connell recorded, the physical context in which he recorded it has largely been erased.

What remains, then, is an absence with a name attached to it. The site sits in the archaeological record not because something was found, but because someone, at some point, noticed something worth writing down, and the landscape has since moved on without explanation.
