The Transfiguration Church in the village of Ikonnikovo, Gorodetsky District, was built in 1811. Side chapels were likely added to the refectory in the early 20th century. The building dominates the surrounding flat landscape. The church is designed in the traditional "ship" composition. Its dimensions are 39.4×22.3 m. The basement, walls, vaults, and tent are made of red brick, while the facades are plastered. The architecture combines Baroque volumes and flat decor in the Art Nouveau style, added during renovations in the 1910s.

The massive cubic base of the temple, covered by a four-pitched roof, is topped with a closely arranged blind five-domed structure. To the west, a rectangular refectory of lesser height adjoins the base, featuring protruding side chapels, and to it, a square three-tiered tent bell tower. To the east, a narrower five-sided altar apse, equal in height to the refectory, adjoins the base. The facades of the base are designed in three tiers and divided by order pilasters. The temple and altar have steeply pitched roofs with the characteristic curved shape of Baroque. A distinctive feature of the church is its compact silhouette with an unusual arrangement of side domes facing the cardinal directions, centered on each facade. The side domes are set on figurative cubic bases with round lucarnes.

The temple is covered by a closed eight-section vault on trompes with narrow diagonal faces and lucarnes along the axes of the main sections. The apse, covered by a section vault with discharges above the windows, is connected to the temple by three openings. The refectory is covered by a semi-closed vault with discharges, while the side chapels have Monier vaults.

The church is surrounded by a cemetery and a fence with gates made of red brick and ornate wrought-iron leaves. The site is of interest as an example of a rural parish church from the early 19th century, featuring an archaic Baroque composition and decor in the spirit of provincial Art Nouveau from the early 20th century.

The temple is in a state of emergency. In two places, the brick vault of the refectory is significantly damaged, and its rafter roof has been lost. The metal roofs of the temple and altar are damaged. The crowning dome and the upper part of the bell tower's tent have been lost. The southern dome of the temple has collapsed, while the eastern and northern domes have tilted, and the crosses are damaged. The northwest corner of the bell tower's octagon is destroyed, and the roof over its base has been torn off. The plaster layer on the outer walls, along with decorative elements, is mostly chipped away. The brickwork is in poor condition, especially at the top. The upper tier windows of the temple are boarded up, and all window glazing has been lost. The basement is covered with lichens and moss. The canopy of the southern porch is destroyed. The interior of the church is completely lost. The crowning parts and brickwork of the gates are significantly damaged, and their metal leaves are partially lost. The brick fence is damaged in places. Dense thickets of trees and shrubs around the church hinder external visibility and prevent the walls from airing out.
