The enclosure measures roughly 102 metres north to south and 97 metres east to west, its rounded corners and substantial surrounding bank giving it the feel of something built with deliberate permanence. That bank runs between six and eight and a half metres wide, rising up to three metres on its outer face, and is accompanied on most sides by a fosse, the old term for a ditch cut to deepen the apparent height of the bank seen from outside. The southwest side breaks the pattern: here the fosse is absent, and a wide entrance, now blocked, once opened onto an internal roadway still partly legible in the landscape as a scarp and a flanking stone wall.

The feature was noted by the antiquary T. J. Westropp in 1918, and his observation was later incorporated into the Archaeological Inventory of County Wexford published in 1996. The entrance on the southwest, wide at seven metres and now blocked, leads internally toward rectangular enclosures at the northern corner that are considered probably modern additions rather than original fabric. The more likely original entrance is a narrower gap of two and a half metres on the northeast side, accompanied by a causeway crossing the fosse. What the enclosure was originally built for remains unclear, though its scale and form are consistent with early medieval ringwork-type enclosures sometimes associated with ecclesiastical or high-status secular use. The strongest suggestion that this was more than a purely agricultural or defensive feature comes from a single object found inside the perimeter at the southern corner: a bullaun stone, a rounded boulder hollowed into a shallow basin by repeated grinding or ritual use, measuring roughly 90 centimetres by 45 centimetres with a basin 28 centimetres across and eight centimetres deep. Bullaun stones are most commonly associated in Ireland with early Christian sites, where they served purposes ranging from grain-grinding to devotional practice, and their presence is often taken as a quiet indicator of ecclesiastical activity nearby, even when no other obvious trace of a church or settlement survives.
