The subtle arc in the ground is a likely remnant of an early ecclesiastical enclosure, the kind of roughly circular boundary, usually formed from a raised bank or ditch, that defined the sacred precinct of an early Irish monastic or church site. These enclosures are easily missed precisely because they were never built from stone; they survive, when they survive at all, only as soft undulations in the landscape.

The site was identified by the researcher Swan in 1988, who noted the earthwork curve and interpreted it as possible evidence of such an enclosure associated with the existing graveyard. This kind of survival is not unusual in Ireland, where early medieval church sites were often later absorbed into parish use, with the original boundary quietly persisting beneath centuries of grass. The graveyard itself, recorded separately, appears to have grown up within or immediately alongside what may once have been a defined religious compound, its eastern edge still faintly tracing that older perimeter.
