The enclosure measures roughly 30 metres across, defined by a wide, low bank and an outer fosse, a shallow defensive or boundary ditch dug around the perimeter. The bank itself is modest, rising only half a metre on its outer face, but it is broad enough, between five and six metres wide, to suggest something deliberate and considered rather than a casual field boundary. What makes it quietly odd is the absence of any visible way in.

By the time the Ordnance Survey mapped this part of Wexford in 1839, the enclosure was already being encroached upon. A field bank running roughly north-east to south-west had cut across its south-eastern arc, trimming what would originally have been a complete circle of around 35 metres in external diameter. That truncation tells its own story about the gradual absorption of earlier, unidentified features into the working landscape of post-medieval farming. The enclosure's original function remains unclear, as embanked enclosures of this kind can belong to a wide span of periods and uses, from early medieval settlement to stock management. About 90 metres to the west lies a separate and distinct moated site, a rectangular enclosure typically associated with Anglo-Norman manorial settlement of the 12th to 14th centuries, though the two features are not known to be directly connected.
