The construction of the domestic church of John the Baptist at the archbishop's house began after the main works on the administrative-residential building were completed at the end of 1880. In 1888 and 1891, civil engineer P. Maslennikov refined the project, prepared the estimate, and conducted calculations for the stability of the vaults and arches of the church. He also oversaw the construction, which was completed by 1897. In 1900, the church was first expanded by adding to the refectory and enriching the interiors under the guidance of architect A. A. Folbaum. In 1914, the church was further enlarged with a large extension to the southern facade of the refectory, bringing the southern entrance closer to the main street. This entrance was decorated with a large arched opening with stained glass. The archbishop's house, along with the church and garden, formed a block and a building site for the New Cathedral Square and the main street, Voskresenskaya, now Mira Avenue.

The church building adjoins the archbishop's house on the southern side, forming the corner of Mira Avenue and Gorky Street.

The structure includes the original core: a cross-shaped church, a square-based temple with a rectangular altar and two side chapels, an elongated refectory, and a wide base for the bell tower, as well as later extensions on the southern and northern facades, emphasizing the transverse axis of the volume. A wide octagonal structure is placed on the square base of the temple, with narrow diagonal faces completed with false lucarnes topped with triangular pediments.

The faces on the cardinal points contain high rectangular windows that cut into the crowning cornice. The windows are framed with semi-columns with melon-shaped capitals and topped with kokoshniks of keel-like shape. Similar kokoshniks frame the false round lucarnes above the altar and the southern chapel. The corners of the octagon are decorated with semi-columns with necking. The volume of the temple is topped with a low drum with eight faces, serving as the base for the tented roof, and a low spherical roof above the vault of the temple. The wide profiled cornice of the lower tier of the church is supported by corner pilasters.

The plinth made of granite blocks is finished with a profile of a roll and two shelves. The preserved volume of the bell tower, a two-tiered square, protrudes on the western facade, repeating the design of the side risalits of the eastern facade of the administrative-residential building. The character of the window and pilaster framing is similar on both buildings of the house. They are repeated on the later extensions, but are not plastered and are somewhat rough. The end of the southern projection is pierced by a huge arched opening filled with stained glass. On either side of the opening, massive semi-columns with square necking support sections of the cornice of the lower tier.

Above the wide wedge-shaped lintel rises a blind gable, above which a small dome was placed. The main structures are visible even in the cramped volume filled with ceilings and partitions, allowing for the recreation of the church's interior. The vast space of the refectory and the chapels connected to it by large arched openings contrasts with the semi-enclosed relatively small space of the temple and narthexes. The temple is covered by an eight-bay vault, resting on a structure of alternating trapezoidal sails and troughs, pierced by window openings.

Above the chapels and narthex, there are barrel vaults with troughs, while above the square western extensions, they are vaulted. The profiles of the arch frames, some ceiling ties, and fragments of tempera paintings on the walls and vaults, hidden under lime and oil paints, have been preserved.

The dimensions of the church along the west-east axis are 25 meters, and along the north-south axis, 18 meters.

The tented finishes of the church and the ringing tier of the bell tower have been lost. The interior space is divided by an inter-floor ceiling on steel beams and partitions. A capital three-flight staircase has been constructed. The pattern of the stained glass has been altered.

This monument of cult architecture from the second half of the 19th century in the Russian style is distinguished by its unique and complex volumetric-planning composition. It is part of a multifunctional building complex and retains significant urban-forming role due to its large size, richness, and variety of forms and silhouette.

In 2002, a monument to physician and priest Valentin Felixovich Voiko-Yasenevsky, who worked during the war in an evacuation hospital, was installed in front of the building.

In 2012-2015, repair and restoration work was carried out. A late wooden extension, which had no historical value, was dismantled, drainage and paving were arranged around the perimeter of the building, new porches and entrances were created, wooden roof elements were repaired and reinforced, effective drainage of atmospheric precipitation was organized, architectural wooden decor, window fillings, shutters, doors, floors, and ceiling decor were restored and recreated. Works were also carried out to install engineering networks considering the style of the cultural heritage object, replacing existing ceilings with reinforced concrete ones, restoring stairs and floor coverings, painting the temple, and landscaping the area with the construction of a brick fence and restoration of the historical fence.
