What survives is a faint circular depression, roughly four metres across internally, that may once have been a dwelling. Extending northward from it for another four metres are two parallel rows of upright stone slabs, set about seventy centimetres apart and closed off at the northern end by a single slab. The rows are too narrow and too deliberate to be incidental, and the most plausible explanation is that they represent the remains of a souterrain, an underground stone-lined passage of the kind built throughout early medieval Ireland, typically for storage or refuge.

The archaeologist R. A. S. Macalister noted the souterrain in 1899, and his account adds a layer that the ground itself no longer offers. He recorded that the passage terminated at its northern end just outside a circular lios, a ringfort or enclosed settlement, roughly four and a half metres in diameter. That enclosure has since vanished entirely, leaving no surface trace. The pairing of a souterrain with a lios is consistent with what is known from comparable sites across Munster, where souterrains were often constructed within or immediately adjacent to ringfort enclosures, their entrances tucked close to the interior bank. Here, the enclosure that once gave the souterrain its context is gone, and the stone rows survive only as a fragment of something whose full form can now only be inferred.
