The Church of St. Nicholas the Wonderworker is a square-plan single-domed structure that rises above a semicircular apse and a square refectory, which are equal in width. It was previously adorned with a single dome covered in scales, set on a faceted blind drum. At the corners of the square and the refectory, there are pilasters supporting the cornice. A frieze of stepped triangular consoles runs under the cornice, completing all volumes of the building. Small rectangular windows on the side facades of the main volume and the refectory are arranged along two axes: in the refectory, they are shifted to the east, while in the square, they are at different levels. The window frames, slightly set back from the opening, resemble Naryshkin Baroque, but between the pyramids at the upper corners, there is an archaic keel-shaped kokoshnik. Some windows still have grilles. The central space of the temple is completed with a cross vault. The altar's conch and the barrel vault of the refectory are complicated by arches above the windows. All parts of the temple are connected by wide arched openings.
