The walls have sunk so low that their internal face stands no more than thirty centimetres above the ground in places, and the whole structure is heavily overgrown. Yet embedded in the western outer wall-face is cyclopean masonry, a technique involving very large, irregularly shaped stones fitted together without mortar, more often associated with prehistoric construction than with Catholic chapel-building. That detail alone suggests the site has a longer and stranger history than its nineteenth-century map names imply.

By 1842, when the Ordnance Survey recorded it on their six-inch map, the building was already ruinous, labelled simply as 'Correen R.C. Chapel (in ruins)'. Later OS editions, from 1897 and 1920, give it a different name entirely: 'Templepatrick', the temple prefix indicating an early ecclesiastical dedication. The rectangular footprint, estimated at between ten and thirteen metres east to west and just over five and a half metres north to south, sits within a wider ecclesiastical enclosure, itself set in the western part of a graveyard. A gap of around 1.3 metres near the western end of the south wall is thought to be the remnant of the original doorway. Among the more arresting features is a large upright stone, 1.7 metres tall, positioned near the centre of the north wall, as well as a vertically set quoinstone in the south-west corner. Quoinstones are the dressed corner-stones used to stabilise and define the angles of a wall, and this one at 0.72 metres high is among the few details that remain clearly intentional. Elsewhere in the south-west part of the graveyard there is a holed stone, a type of perforated rock that appears across early Irish ecclesiastical sites in contexts ranging from oath-taking to ritual. And approximately twenty metres to the east-south-east of the church, historic maps and other sources point to the site of a possible leper hospital, a reminder that such institutions were commonly established on the margins of settled communities, often in proximity to religious houses that could offer some form of care.
