The mound itself is modest enough, a roughly oval rise of earth and stone measuring about ten metres along its longer axis and just over a metre in height, sitting quietly among scrub and rock outcrop. What gives it particular interest is what lies inside: a souterrain, an artificial underground passage or chamber typically constructed during the early medieval period in Ireland, often associated with nearby settlement sites and used variously for storage, refuge, or concealment. The entrance to this one opens near the south-eastern edge of the mound.

Around the perimeter of the mound, traces of stone revetment, a facing of stones used to retain and stabilise the earthen core, are still visible, and are best preserved along the southern and western sides. This kind of structural detail suggests the mound was deliberately engineered rather than simply accumulated. The presence of a ringfort approximately 110 metres to the east is a significant detail; ringforts are the most common monument type in the Irish archaeological landscape, circular enclosures of earth or stone that served as farmsteads during the early medieval period, roughly the fifth to twelfth centuries. The pairing of a souterrain-bearing mound with a nearby ringfort fits a pattern seen elsewhere in Ireland, where souterrains were integral to the organisation of early rural settlement, sometimes dug beneath a fort's interior, sometimes positioned just outside it.
