A rath, as these earthen enclosures are known, was typically formed by one or more roughly circular banks and ditches, enclosing a domestic settlement during the early medieval period. This one, measuring approximately 35 metres in diameter, cannot be made out at ground level at all, which places it in a quietly melancholy category of sites: archaeologically recorded, historically real, yet imperceptible to anyone walking over it.

The Ordnance Survey's six-inch map of 1846 recorded the rath as a complete circular enclosure, giving us at least a fixed point in time when its outline could still be traced on the ground or from cartographic survey. By 1894, when the revised six-inch map was produced, only the south-western half of the feature survived, and even that remnant was already pressed up against a north-west to south-east field boundary, the kind of agricultural division that, over generations, quietly consumes earthworks. The loss of the north-eastern arc in the intervening half-century points to the relentless levelling that accompanied land improvement and enclosure across rural Ireland during and after the nineteenth century. Adding another layer of interest, there is a possible souterrain associated with the rath. A souterrain is an underground stone-lined passage or chamber, typically built during the early medieval period for storage or as a place of refuge, and their presence within raths is not uncommon across Munster. Whether this one is intact below the surface remains an open question.
