Cropmarks, the faint differential growth patterns that aerial photography can reveal in cultivated fields, trace its outline across roughly thirty metres in each direction. The shape is not quite a full circle; one side flattens into a straight line, giving it that characteristic D-form that distinguishes certain enclosures from the more regular raths, or ringforts, found across Ireland.

What makes this site particularly interesting is the patchwork of boundaries that define it, some ancient, some more recent, and not always easy to disentangle. The southern edge follows a field bank that also serves as the townland boundary between Ballyregan and Cumshinstown, meaning the line of this enclosure has been quietly encoded into the landscape as an administrative marker long after its original purpose was forgotten. The eastern side corresponds to a field bank and drain that appears on Ordnance Survey maps from both 1839 and 1940, suggesting these features persisted as working boundaries across at least a century of farming. On the western and northern sides, the curved arc of a fosse, a defensive or demarcating ditch approximately three metres wide, shows up only as a cropmark, its physical form long since levelled. A rath, a type of circular earthwork enclosure typically associated with early medieval settlement and farming, lies around eighty metres to the east, raising the possibility that the two sites were related, part of a wider pattern of activity in this corner of Wexford.
