The Church of Nicholas the Wonderworker is built of brick, covered with plaster on the outside, and painted in ochre color. The architectural composition includes a five-domed temple with a narrow apse, a cross-oriented refectory, and a three-tiered bell tower. The corners of the two-light square of the temple, the almost square apse, and the rectangular refectory are decorated with brackets and rounding on the outside. The temple is adorned with octagonal drums, on which onion-shaped domes with scaly metal covering are installed. The central drum is larger and has windows, while the others are blind. The bell tower consists of tiers that gradually decrease in height. The finishing octagonal drum of the bell tower is topped with a spire. The symmetrical three-axial facades of the temple are divided by a floor cornice, which continues on the apse, refectory, and the lower tier of the bell tower. The cornice features a series of two-tiered teeth. On the central axis are the southern and northern entrances to the temple. The doorways and windows of the first and second lights are highlighted by wedge-shaped locks. The crowning cornice of the square is similar to the floor cornice. The facades of the apse and refectory repeat the motifs and shapes of the lower tier of the square. The central part of the refectory facade is distinguished by a triple window with a sandrik, which has a semicircular elevation in the center. All tiers of the bell tower are decorated with large arched openings with three-part wedge-shaped locks. On the first tier, the walls are adorned with Tuscan pilasters, while on the second and third, with half-columns of the same order. The facades of the two lower tiers are completed with triangular pediments featuring two-tiered teeth in the cornice.
