No wall, no earthwork, no visible depression announces itself at ground level. What survives instead is a cropmark, a phenomenon where buried features affect the growth of overlying vegetation in ways that only become apparent when viewed from altitude. The circular outline, defined by a single continuous fosse, which is a ditch typically cut to delineate or defend an enclosed area, shows up with quiet clarity in aerial and satellite imagery.

The enclosure at Ballycarney was first reported by Jean Charles Caillére, and it has since been confirmed in imagery from multiple dates, including captures from Google Earth in June 2017 and March 2022. It sits on sloped ground with a small east-west stream running approximately 140 metres to the south, a positioning that would have made practical sense to whoever originally dug the fosse, whether for agricultural, domestic, or ritual purposes. Circular enclosures of this general type are well distributed across the Irish landscape and span a considerable range of periods, though without excavation the precise date and function of this particular example remain open questions.
