The spot sits within what was once a circular enclosure, though the enclosure itself has been so heavily altered over time that its original form is now difficult to read on the ground. What remains most legible is a series of small depressions in the south-eastern quadrant, and the faint geometry of a buried structure pressing up through the turf.

The feature is a souterrain, a type of dry-built underground passage or chamber found widely across early medieval Ireland, typically associated with settlement sites and thought to have served for storage, refuge, or both. At Cnoc na nGabhar, one of the depressions offers a small opening beneath the partly visible roof slab, through which a drystone-built passage can be seen extending at least two metres to the south. The site sits within the broader landscape of the Dingle Peninsula, a part of Kerry long settled and intensively used, and was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the area. The circular enclosure with which the souterrain is associated appears on Ordnance Survey maps, though its current condition reflects significant modification from its original form.
