The ruined chancel, its ivy-clad walls enclosing a partially overgrown interior used for burials since at least 1815, sits directly beside a nave that is still roofed and in use as a hall. The two halves of what was once a single building are now separated by a blank wall, and a late medieval four-storey tower clings to the south-west corner, its crenellations gone but its bell still sitting in a bellcote added to the north wall. The whole arrangement occupies a single graveyard that also contains a replacement church, built in 1905, making this one of those quietly layered sites where several centuries of ecclesiastical improvisation are visible at a glance.

The church was already showing signs of uneven survival by 1615, when the nave was reported in repair but the chancel already ruinous. The nave continued in use as a Church of Ireland church for another three centuries, with the chancel arch apparently converted into an east window at some point before 1694, when the nave was recorded as being in good repair. That conversion, noted by the antiquarian Power, obliterated the visual connection between the two spaces and effectively sealed the chancel off as a separate, deteriorating structure. The tower is considered late medieval in date and the church itself was notably large for a parish church, a scale that may reflect its association with Barryscourt Castle nearby, the seat of the powerful Barry family. On the west face of the tower, an oval plaque was erected in 1688 by Sir James Cotter, whose family seat was Anngrove House; nearby, a more elaborate aediculated memorial to the Dobson family, dated 1789 and also connected to Anngrove, has been recently vandalised. The 1842 Ordnance Survey six-inch map labels the site as an abbey, though there is no supporting evidence for any monastic foundation here.
