The arch divides what was once a modest rectangular structure, just over nineteen metres long and a little over eight metres wide, into nave and chancel, giving the interior a formal arrangement that speaks to inherited liturgical habit rather than any grand ambition.

The church most likely dates from around 1721, a date suggested by its close resemblance to a near-identical structure built at Schull in the same period. The reason a new building was needed at all is recorded in a much older note: the previous church on or near this site had already fallen into ruin by 1699, according to Brady's research cited in the mid-nineteenth century. What replaced it was a plain but considered piece of work. The west gable carried a bellcot, a small masonry bracket designed to hold a bell above the roofline, and was pierced by a central doorway. Light entered through two window openings in the north wall and single openings in the south and east walls. Shallow wall-presses, small recesses built into the masonry, survive near the east ends of both the north and south walls, likely used for storing liturgical items. A cross slab, a flat stone carved with a cross and typically marking an early Christian burial, lies at the east end of the church, hinting at a much longer history of religious use on this ground before the eighteenth-century structure was ever raised.

The ruins sit within a graveyard that remains in use, so access is straightforward. The chancel arch and the surviving window openings repay a close look, as does the cross slab at the east end, which sits quietly among later grave markers without much to distinguish it at a glance.
