Its entrance lies roughly seventy centimetres below the present ground surface, and a collapsed lintel, one of the stone slabs that would once have roofed the entry passage, has fallen in such a way as to seal it entirely. The site does not appear on Ordnance Survey maps, which means it has existed quietly in this field, uncharted and largely unvisited, while the landscape around it was surveyed, divided, and named.

A souterrain is an artificial underground structure, typically a stone-lined passage or chamber, built during the early medieval period in Ireland and used variously for storage, refuge, or as an annexe to a nearby settlement. This one sits within a roughly circular raised platform about twelve metres across, which still stands approximately eighty centimetres above the surrounding ground on its western side. That kind of earthen platform often signals the remains of a ringfort or enclosed farmstead, and the fragments of drystone walling found directly above the souterrain entrance suggest that some associated above-ground structure once stood here too, though too little survives to say with certainty what form it took. The combination of the platform, the walling remnants, and the underground passage points toward a settlement of some significance, likely dating to the early medieval centuries when souterrains of this type were in common use across Munster.
