The bank that once defined its boundary has largely dissolved back into the ground, but enough survives to trace the circuit of what was once a carefully enclosed religious space. At its centre sit the ruins of a church, themselves surrounded by a rectangular graveyard, the two shapes, one ancient and round, one later and straight-edged, sitting inside each other like evidence of two different ideas about sacred space laid down across the centuries.

Circular ecclesiastical enclosures of this kind are a well-recognised feature of the early Irish church. Where a Roman or medieval European parish would typically organise itself around a rectilinear plan, early Irish monastic and church sites were commonly enclosed within a roughly circular or oval boundary, thought to reflect both practical land management and a symbolic sense of sacred separation from the world outside. The enclosure at Abbert Demesne sits on a slight rise beside a former demesne lane, about 80 metres west of a stream, a position that echoes the preferences of early church founders for ground that was elevated enough to be visible and defensible, yet close to fresh water. The rectangular graveyard within it suggests later use of the site, as communities continued to bury their dead within the old sacred boundary long after the original monastic or ecclesiastical function had faded.
