Whether it survives intact is another matter entirely. The ringfort it once served has been levelled, and the souterrain itself leaves no visible trace on the surface today.

The only real clue to its existence comes from a 1934 observation by a researcher named Bowman, who recorded a depression in the south-western part of the fort as indicating the presence of a souterrain below. Depressions of this kind are a familiar sign to field archaeologists; as the roof of an underground structure gradually collapses or the fill above it settles, the ground above sinks slightly, leaving a subtle hollow that can persist for centuries. It is a quiet kind of evidence, easy to miss and easy to misread, but meaningful once you know what you are looking at. The ringfort itself, a circular earthwork enclosure of the kind built in their thousands across early medieval Ireland, has since been removed from the landscape entirely, leaving the souterrain, if it remains, orphaned underground with nothing above it to suggest its origins.
