Local knowledge holds that a souterrain, an underground stone-lined passage of the kind commonly associated with early medieval settlement, was formerly visible at this site, though it has since disappeared from view. That lost feature is perhaps the most intriguing detail about this quietly complex enclosure on the Dingle Peninsula, a rath that has absorbed several centuries of agricultural modification without quite losing its original shape.

The site is a univallate rath, meaning it has a single enclosing bank rather than the multiple concentric rings found at more elaborate examples. Subcircular in plan, it sits on a very gentle east-facing slope overlooking the low marshy ground around Trabeg, with an internal diameter of around 24 metres. The southern and eastern sections of its bank have been replaced by modern field walls, as farming practicality gradually colonised the perimeter, but the remainder still stands up to 1.3 metres high. At the north-west, part of the inner face retains its original construction method, with upright stone slabs set against the bank face. There are several breaks in the earthwork, the widest on the western side measuring 2.5 metres across and partly blocked by a single upright slab, which may or may not mark an original entrance. At the centre of the interior, two upright slabs and a scattering of fallen stones outline what appears to be a small hut site, enclosing a modest area of roughly 4 by 2 metres. These raths were typically the farmsteads of early medieval Ireland, occupied between roughly the fifth and twelfth centuries, and the combination of a probable dwelling site, a structural bank, and a now-vanished souterrain fits that domestic pattern precisely. The detail about the souterrain comes from local information rather than excavation, which leaves open the question of what else the ground here might still hold.
