The western gable still stands close to its original height, built from large, well-shaped limestone blocks, with an off-centre doorway nearly two and a half metres tall and a window embrasure just above it. Inside, a row of three limestone corbels, brackets projecting from the wall face to carry roof timbers, lines the inner surface below the present top of the doorway, with a corresponding beam socket still visible at the western end of the north wall. The south-eastern corner of what was once the same building has been absorbed into a Church of Ireland church that stands nearby in the same graveyard, making the original plan legible only if you know to look for it. At over thirty metres in length, this was considerably larger than a typical late medieval parish church in County Cork, which raises questions the surviving masonry alone cannot answer.

Those questions include whether this was ever an Augustinian friary founded by the O'Callaghans, a claim some sources make but which remains ambiguous. What is clearer is that the church was functioning as a perpetual vicarage by 1469, and that it remained in the possession of Mourne Abbey until 1577. A visitation record from 1615 found it in good repair, but within sixty years it had deteriorated, and by 1694 it had lapsed into ruins, attributed at the time to damage done by 'the Irish in the late war', a reference to the Williamite conflict of the 1690s. Earlier observers noted further details now harder to verify: a sacrarium, a small liturgical basin or recess associated with sacred water, was recorded adjacent to the western gable in the 1930s, and a field to the west of the ruins was once reported to have been flagged, hinting at a wider complex that has since disappeared entirely into the ground.
