The shape of its boundary wall is the clue: rather than the irregular outlines typical of later medieval burial grounds, the enclosure follows a curved, roughly quadrantal form that some researchers read as the fossilised trace of an Early Christian ecclesiastical enclosure. These enclosures, common across Ireland in the early medieval period, typically surrounded a church, monastic cells, and associated activity, their circular or oval boundaries marking sacred space as much as practical territory. Here, the shape of the wall is essentially all that survives of that possible history.

The argument was set out by Swan in 1988, who pointed to the graveyard's boundary as evidence for an Early Christian origin at this site. The church itself sits in the northern quadrant of the enclosure, a positioning that is not uncommon in early ecclesiastical layouts. Adding further texture to the landscape, Low's Castle stands roughly 80 metres to the northeast, suggesting that this small corner of Westmeath accumulated layers of significance over several centuries. It is worth noting, however, that the case for an Early Christian enclosure here remains unproven. No clear physical evidence has been identified to confirm the enclosure's existence beyond the suggestive geometry of the graveyard wall, and the site sits in that category familiar to Irish archaeology: intriguing but unresolved.
