Most of the other openings have been robbed out over the centuries, their dressed stone carried off for later construction, but that single window survives to give the ruin a quiet elegance. The church measures roughly fifteen and a half metres long by six metres wide, oriented east to west in the standard medieval fashion, with a later south transept added at some point after the original build. The transept itself is lit by a twin-light window topped by a circular ope, a small round opening above the paired lights, a detail that suggests some ambition in its design even at this modest scale.

The site sits above Lough Corrib to the north-east, and the surrounding graveyard, though largely modern in its present use, may preserve the footprint of something far older. Its northern boundary wall follows a noticeably curved line, and curving enclosure walls of this kind are often read by archaeologists as the remnant outline of an early medieval ecclesiastical enclosure, the kind of roughly circular or oval boundary that defined a monastery or sacred site in Ireland from around the sixth century onwards. If that interpretation holds here, the place may have begun as the monastery of St Cummin, an early Christian foundation tentatively identified with this location by several historical sources. St Cummin, associated in tradition with the broader Lough Corrib region, would place the origins of this site well over a thousand years before the medieval stonework now standing.
