It was recorded by name on the 1838 edition of the Ordnance Survey six-inch field map, placed within the interior of a cashel, the type of early medieval stone-walled enclosure commonly associated with farmsteads or minor lordly residences across the west of Ireland. By the time anyone thought to look again, there was nothing to see. No opening, no hollow, no surface trace of any kind.

The cashel itself survives as a recorded monument, but the cave it once contained has vanished from the landscape entirely, leaving only its cartographic ghost. Whether it was a natural fissure, a souterrain (an artificial underground passage built for storage or refuge, often associated with early medieval settlement), or something else entirely is not recorded. McCaffrey noted it in 1952, citing it by number and location, but the detail stops there. The 1838 map remains the clearest evidence that something was once considered significant enough to name, even if no one now living has seen it.
