To the south-west and west of Leny graveyard, traces of a circular enclosure are just visible from the air, the kind of subtle earthwork that disappears entirely at ground level but resolves into a faint arc when seen from above.

Ecclesiastical enclosures of this type are the curved boundaries, usually roughly circular, that once defined the sacred precinct of an early Irish Christian site, separating the spiritual from the secular in a very literal, physical way. They are often the earliest surviving evidence that a place was once a functioning religious community, predating any standing stonework by centuries. This particular site was identified by Swan in 1988, who noted the evidence of a circular enclosure lying to the south-west of the existing graveyard. It is the kind of find that quietly reframes an otherwise unremarkable rural burial ground, suggesting that people have been marking this patch of Westmeath as set apart for a very long time.
