Sitting on a gentle west-facing slope in poor upland pasture near Ballynasculloge, the circular earthwork, roughly thirty metres in diameter, exists visibly only from the air. At ground level it leaves no trace the eye can follow.

The enclosure came to light through aerial photography, appearing as a cropmark, a phenomenon where buried archaeological features influence the growth of surface vegetation above them, causing subtle variations in colour and density that become legible only when viewed from altitude. The site was identified through photographs held in the GSI aerial photographic collection, as well as orthographic imagery from 1995. Enclosures of this general type are a familiar feature of the Irish landscape, typically associated with early medieval settlement, though without excavation it is difficult to say anything more precise about the origins or function of this particular example. What is clear is that it has survived, if invisibly, beneath centuries of upland grazing.
