Built sometime after 1622, this rectangular gabled building served the local community for over two centuries until a new chapel of ease was constructed in nearby Cornagill townland in the mid-nineteenth century. The church’s rubble walls, reinforced with rough ashlar quoins and dressed stone blocks, measure 13.6 metres by 5.6 metres internally and retain traces of their original plaster coating on the interior, whilst the exterior shows remnants of harling and slate hanging on the western gable.

The architectural details reveal the building’s 17th-century origins through its distinctive window arrangements. A large window pierces the eastern gable, featuring slightly splayed openings and a segmental rear arch, whilst five additional windows punctuate the north and south walls; three along the southern wall and one at the eastern end of the northern wall. Interestingly, the eastern section of the south wall shows evidence of later modification, with an internal offset reducing the wall thickness about half a metre above the current floor level. The two windows in this section were originally positioned at this lower level but were subsequently raised, suggesting the church underwent alterations during its long period of use.

The main entrance, set into the western gable, features a round-headed doorway with a segment-headed rear arch and evidence of its original timber frame. The elevated graveyard surrounding the church has necessitated stone retaining walls along the pathways to both the north and south of this entrance, creating a somewhat sunken approach to the building. These surviving features, documented in the Archaeological Survey of County Donegal, provide a tangible link to the religious life of this rural community from the post-Plantation period through to the Victorian era.
