The two-story church is rectangular in plan (4.2 × 3.5 m; height 7.5 m) and dates to the High Middle Ages. It is built of large, partly worked rubble stone in regular courses. It is damaged: the roof covering and part of the cornice have collapsed, and much of both eastern corners is broken away. Later, for reinforcement, a thick wall of rubble stone (about 0.6 m wide) was built against the west wall through its full height, both its ends rounded so as to cover both western corners of the building to their full height. The cornice and roof were evidently renewed at the same time.
