What gives the site a quietly odd quality is a detail tucked into the northeast corner of the building: a mortuary vault, a sealed burial chamber constructed as part of or against the church structure, bearing the date 1796 carved directly into the quoin stone at its southeast corner. A quoin stone is one of the dressed corner blocks used to reinforce and finish a masonry angle, and cutting a date into one was a deliberate act of permanence, a way of anchoring the vault's existence in the fabric of the building itself.

The church is rectangular in plan, with round-arched windows set into both the north and south walls and a high round-arched doorway in the west gable. This arrangement, plain and functional but with some care given to the proportions of the openings, is consistent with late eighteenth-century ecclesiastical building in rural Ireland, when Church of Ireland congregations in particular were constructing modest preaching houses across the country. The mortuary vault attached at the northeast angle suggests a family of some local standing wished to secure burial within or immediately beside the church building itself, a practice that carried considerable social and religious weight. The graveyard surrounding the church is large and rectangular, and its headstones run from the nineteenth century into the twentieth, indicating continuous use across a long period.
