But from the air, the ground tells a different story. An aerial photograph, reference GB90.BM.23, reveals a cropmark tracing the outline of a curvilinear enclosure, its circular or oval form defined by a fosse, which is a defensive or boundary ditch dug into the earth. The enclosure itself has long since disappeared at ground level, absorbed into centuries of agricultural work, but the differential growth of crops above the buried ditch still betrays its presence when conditions are right.

The site sits on the north-western edge of a flat ridge in undulating terrain, with the ground falling away steeply towards a small valley to the north-north-west. In every direction but that one, the elevated position would have offered good to extensive views across the surrounding landscape, a quality that was rarely accidental in early settlement and enclosure sites. The north-west outlook is interrupted by a neighbouring hill, which may itself have influenced where precisely the enclosure was placed. Curvilinear enclosures of this kind are broadly associated with early medieval settlement in Ireland, sometimes surrounding a dwelling, a farming compound, or a site of local significance, though without excavation the precise date and function of this particular example remain open questions.
