That label implies something substantial enough to name and record across nearly a century of cartography. What survives on the ground today is considerably less dramatic: a shallow, nettle-filled hollow and what may be a single roof lintel, half-buried and easy to miss.

The cave sits within the western sector of a rath, the circular earthwork enclosure that was the standard form of enclosed farmstead in early medieval Ireland. Raths were typically defined by one or more banks and ditches surrounding a central living area, and it was not uncommon for them to contain a souterrain, an underground stone-lined passage or chamber used for storage or as a place of refuge. This feature at Lisnadrisha is almost certainly the remains of one such structure. McCaffrey, writing in 1952, catalogued it among similar features in the area, which suggests it was at least partially traceable at that point, even if little remained above the surface. The fact that both the 1838 and 1933 maps name it indicates it had some local identity and visibility well into the twentieth century. Whatever caused its collapse or infilling has since reduced it to that single ambiguous stone and a depression in the earth.
