Three sides, the south, west, and north, were defined by their own walls, but the eastern side was left open, coinciding instead with the boundary of the wider ecclesiastical enclosure in which the church sat. That detail is quietly odd: the enclosing wall of the entire site effectively served as the church's own east wall, suggesting a deliberate and economical piece of planning by whoever laid the place out.

By 1916, when the Ordnance Survey recorded it on their six-inch map, the building was already noted simply as 'Ch. (in Rns.)', a church in ruins, reduced to the sunken rectangle that can still be read in the landscape today. The site sits on the eastern edge of an ecclesiastical enclosure, the kind of roughly circular or oval boundary that typically marks an early Irish monastic or parish foundation, where a defined sacred precinct was set apart from the surrounding land. Unusually, this church is not alone: a second church lies approximately thirty metres to the south-west, which points to a site of some complexity, perhaps one that accumulated structures across different periods of use.
