Running from the north-west, around to the north, and on to the north-east of a nearby abbey site, the arc is subtle enough to be overlooked entirely on foot, yet distinct enough, when mapped, to suggest that something older than any field system is quietly organising the landscape.

What researchers have proposed is that this curve preserves the outline of an Early Christian ecclesiastical enclosure, a type of roughly circular or oval boundary, often defined originally by a bank and ditch, that marked the sacred precinct around an early monastery or church. These enclosures, common across Ireland from roughly the sixth century onwards, frequently survived not as standing earthworks but as ghosts absorbed into later land divisions, their shape persisting in hedgerows and property lines long after the original boundary itself had disappeared. The scholar Leo Swan noted in 1988 that the field pattern here corresponds with this kind of survival, placing it in relation to the abbey site already recorded in the area. The identification remains a probability rather than a certainty, which is itself a fair reflection of how much of early medieval Ireland exists now, implied rather than visible.
