The Church of John the Theologian is designed in the style of late classicism with a small addition of a porch in the Russian style from the late 19th century on the western side. The completion of the building is lost. The small and modestly decorated temple is interesting for its rare volumetric composition: the square in plan drum is surrounded by wider and lower rectangular parts, elongated along the north-south axis, which form the narthex and altar. On the side facades of the drum, between the protruding parts, there are two-columned porticoes in antae, which are the main decoration of the temple. The central parts of the eastern and western facades are highlighted by three-axis risalits. Rectangular windows, some of which are false, have straight architraves, and the walls are decorated with a modest profiled entablature. A feature of the internal structure is the round plan space of the drum, covered by a low domed vault. Along the longitudinal axis, it is connected by arched openings with identical three-part narthex and altar. The clergy house is a small one-story building made of facing brick, characteristic of the eclectic period. The facades are decorated with corner pilasters, combined with a narrow under-cornice belt. The center of the main facade, which has three windows, is highlighted by a shaped attic with an arched attic window, and at the corners are parapet pedestals.
