The church is a hall church (5 × 3.2 m) built of cobblestone, with the structural parts in travertine. It is badly damaged. The entrance is in the south wall (its upper part has collapsed). On the axis of the semicircular apse is one window flanked by rectangular niches. The sanctuary is set off from the hall by a triumphal arch resting on pilasters; the transverse arch rests on corbels. In the center of the north wall is a rectangular niche. In the pediment of the west facade is a cross carved from a single block of travertine.
