Roughly fifty metres across, with softened, rounded corners, it shows up only as a cropmark, the faint differential colouring in growing crops that betrays buried ditches and banks beneath the soil. It takes satellite imagery rather than a shovel to read it at all, which is part of what makes it quietly arresting.

The enclosure was identified and reported by Jean-Charles Caillère, who spotted it on satellite imagery. Its shape is relatively unusual; most early Irish enclosures tend toward the circular or oval, so a square plan with rounded corners invites attention. The structure appears to have a wide inner element, probably a bank, fronted by an outer fosse, which is simply a ditch, and then a narrow outer bank beyond that. This layered arrangement, bank, ditch, bank, is a form of defensive or boundary architecture seen across early medieval and prehistoric sites in Ireland, though the date and function of this particular example remain unconfirmed. It sits approximately five hundred metres north-northwest of Ballyhale Castle, suggesting a landscape that was organised and occupied across multiple periods, even if the connections between its various features are not yet understood.
