Its western doorway retains dressed and chamfered granite jambs, the stonework cut at an angle to soften the edge, though the arch that once spanned them is gone. The building is compact, roughly thirteen metres long and six and a half wide, constructed from uncoursed rubble, the kind of fieldstone and mortar work that was the ordinary currency of rural ecclesiastical building in medieval Ireland. A bellcote at the western gable end would once have carried a bell audible across the valley below.

The church follows a nave-and-chancel plan, the two rectangular spaces arranged end to end in the manner common to Irish parish churches from the medieval period. String courses, horizontal projecting bands of stone, run across the western gable at the level of the wall tops and the window above the door, a detail that gives the facade a spare, deliberate quality despite the roughness of the rubble construction. At the eastern end, a shallow-arched window faces the altar position, flanked by opposing flat-arched windows set into the north and south walls. Small niches cut into each of the southern walls would once have served a liturgical or devotional purpose, perhaps holding a candle or a small statue. Near the western entrance, a granite stoup or font with a circular basin survives in place; a stoup is a small vessel for holy water, typically positioned near a church entrance so that those entering could bless themselves. The building was restored in 1906, and a modern internal buttress now braces the southern wall, a quiet sign of the ongoing effort to keep the structure standing.
