It is the sort of feature that passes unnoticed unless you are looking for it, and it speaks to a building that was, in its day, fitted out with more care than its rubble limestone walls might first suggest.

The church sits on the north side of a natural rise within the graveyard, oriented roughly east-north-east to west-south-west in the manner common to medieval ecclesiastical buildings. Its external dimensions, 21.1 metres by 8.67 metres, make it a substantial single-cell structure, undivided internally, with walls of roughly coursed rubble limestone and dressed limestone quoins at the corners. Two opposing doorways pierce the west end, one pointed arch on the north wall, the other on the south with its surrounds now missing. Lighting was provided by a mix of window types: a round-headed single light on the south wall, an ogee-headed single light on the north, and a two-light ogee window in the east gable. The ogee, a double curve borrowed from late medieval Gothic architecture, appears again in the upper window of the west gable, which carries decorated spandrels, the triangular spaces flanking the arch. Below it sits a plainer, flat-headed window. At the west end, beam-holes in the surviving masonry point to the former existence of an upper floor or gallery, which may have served as a priest's residence, an arrangement not unknown in rural Irish churches of the later medieval period.
