No earthwork rises from the ground, no stone wall traces a curve across the slope. The only evidence that anything is there at all appears from the air, as a cropmark: the faint, differential growth of plants above buried archaeology, where soil disturbed long ago by a circular ditch retains moisture differently from the ground around it, and the crops growing above it betray the outline beneath.

What the aerial photograph reveals is a univallate circular enclosure, meaning a roughly circular space defined by a single surrounding ditch or bank, of the kind associated in Ireland with early settlement, ritual activity, or land enclosure across a broad sweep of prehistory and the early medieval period. The entrance, as far as can be determined, faced roughly to the north-west. Beyond that, the record is sparse. The land has been under tillage, which both helps preserve buried features from the disturbance that deeper ploughing or construction might cause, and makes cropmark detection more likely, since cereal crops in particular respond visibly to what lies beneath. The enclosure was identified through the Cork Archaeological Survey Aerial Photography programme, a systematic effort to document sites visible only from the air across the county.
