Seen from above, however, a very different picture emerges: a near-perfect circle roughly 45 metres across, sitting on a gentle rise just south of the former flood plain of the River Suck in County Roscommon. The enclosure was identified by Jean-Charles Caillere and became visible through aerial imagery captured in January 2021, the kind of discovery that has become increasingly common as satellite photography reveals earthworks that centuries of farming have all but erased from the surface.

The feature is defined by a shallow fosse, essentially a ditch, with a broad but heavily denuded bank running inside it. This arrangement, a bank set within a surrounding ditch, is characteristic of early medieval enclosures found across Ireland, though the site has not been closely dated. Its position is telling: it sits on slightly elevated ground near the edge of land that would once have flooded regularly, a sensible location for a settlement or enclosed farmstead that needed both drainage and proximity to water. What makes the setting more intriguing still is a cashel lying approximately 135 metres to the south. A cashel is a stone-walled enclosure, typically of early medieval date, used to protect a farmstead or small community. The proximity of the two features raises the possibility that they formed part of the same agricultural or domestic landscape, though whether they were contemporary with one another is not currently known.
