Known locally as Christy's Cave, it came to wider attention in 2013 when investigators discovered a shell midden and a small drystone wall just inside the entrance. A midden is essentially a refuse heap, the accumulated leavings of people who ate, worked, or sheltered nearby, and this one held limpet shells alongside the bones of a dog, sheep, and other mammals. It is a modest assemblage, but the combination of structured stonework and food waste in a cave setting suggests the place was used deliberately, not simply passed through.

The dating of the site remains genuinely unresolved. A medieval date was proposed by Lavender-Duncan and colleagues in a 2013 publication, but cave specialist Marion Dowd has noted there is no firm evidence to support that attribution. The bones and shells on the cave floor have been examined, yet they have not yielded a clear chronology. Caves in the Irish limestone karst have been used across an enormous span of human activity, from the Mesolithic onward, and without radiocarbon dates or datable artefacts it is difficult to place Christy's Cave anywhere specific within that long record. The uncertainty is not a gap to be glossed over; it is the most interesting thing about the site.
