The Church of the Holy Trinity is a large five-domed temple with noticeably lowered and reduced apse and refectory. Attached to the western side of the building is a narthex built in the early 20th century. The architecture of the church retains the volumetric-compositional scheme of the 17th century but uses decorative elements of the Baroque. The high two-light square base with a polygonal apse and widely spaced domes on drums has a traditional three-axis structure of the side facades. The walls are topped with a wide assembled cornice and a two-part attic tier with a belt of decorative kokoshniks, and above, separated by a shelf, is a belt of square strips. The tiers of light are divided by a profiled cornice, which, like the crowning one, is supported above paired pilasters that protrude at the corners. The window frames with arched lintels are decorated with Baroque ears and aprons and are completed with panels with arched sandriks. The edges of the drums are adorned with niches.

The square base is covered with an eight-section vault with a ring of the light drum and voice pipes in the troughs. The refectory has a semi-trough vault with arches above the windows, while the apse features a cylindrical vault transitioning into a three-section conch. The interior of the square base is distinguished by its slenderness due to deep vertical niches that unite the openings of the first and second light. The low narthex of the entrance is covered with a box vault.

The original glue painting of the 19th century in the style of Classicism has been preserved on the western wall of the square base, including grisaille cornices and two figures of sleeping angels that flanked the composition “Descent of the Holy Spirit” in the upper tier.

The oil painting from the early 20th century represents a provincial interpretation of the style of paintings by Vasnetsov in the Vladimir Cathedral in Kyiv. It was executed without adherence to iconography and the placement of the old painting, except for the repeated central composition on the western wall. The narrative scenes are few, with single images predominating. The color scheme is based on local cool tones, among which intense blue and gray stand out.

On the eastern trough of the vault is depicted the “New Testament Trinity,” on the western, the Virgin Mary, and on the sides, paired figures of the evangelists. In the intercolumniations of the southern and northern walls, archangels and John the Baptist are depicted in two tiers. On the western wall, flanking the composition “Descent of the Holy Spirit,” are painted “Transfiguration” and “Dormition.” At the bottom, the arch to the refectory is flanked by figures of Princes Vladimir and Alexander Nevsky. On the vault of the refectory is placed the composition “Old Testament Trinity,” and on the western wall, “Exaltation of the Cross” and “Saint Nicholas the Wonderworker.”
