A roughly oval enclosure, approximately fifty metres across, reveals itself through a phenomenon known as a cropmark, where buried features beneath the soil influence how overlying crops or grasses grow and colour, tracing the outlines of structures that have long since vanished from the surface. No earthwork survives here, no raised bank or sunken ditch, just a ghostly impression readable only when the conditions are right and the camera is overhead.

Cropmarks form when buried ditches or foundations affect soil moisture and nutrient levels differently from the surrounding ground. A filled-in ditch, for instance, retains more moisture than compacted subsoil, producing lusher, darker vegetation above it during dry spells, while a buried wall has the opposite effect. The oval shape and rough scale of this enclosure are consistent with a class of early medieval ringfort or enclosed settlement common across Ireland, though without excavation the precise date and function remain unknown. The feature was identified from Google Earth aerial imagery captured on 14 July 2018, with the record compiled by Caimin O'Brien from details supplied by Jean-Charles Caillère.
