To the north of the church that occupies the southern half of the site, a curving scarp line runs across the ground. That gentle ridge in the earth may mark the boundary of an ecclesiastical enclosure, the kind of roughly circular or oval perimeter that early Irish monasteries typically used to define sacred space, separating the spiritual community within from the secular world outside. It is easy to walk past without registering what it might represent.

The graveyard sits within a site associated with an early monastic foundation attributed to St Colman, a figure with strong connections to the west of Ireland. Early monasteries of this type were often modest in their physical remains, their boundaries surviving not as walls but as faint earthworks, ditches, or scarps like the one visible here. The enclosure form was common across early medieval Ireland, and where such boundaries survive, even partially, they can indicate the original extent and organisation of a monastic community that may have functioned well over a thousand years ago. The association with St Colman places the foundation within the broader network of early Irish monasticism, when island sites were frequently chosen for their relative isolation and their practical separation from mainland politics and pressures.
