The bell tower, resembling a tower, reaches an impressive height, which varies from 62 to 74 meters according to different sources. It is located on the red line of the city's central street and represents a multi-tiered vertical structure, serving as a height dominant of Kazan's historical architecture.

The new bell tower of the Epiphany Church was conceived not only as a tower for bells. The first floor housed small rooms for meetings with Old Believers and a church shop, while the second floor contained a temple dedicated to the Finding of the Honorable Head of John the Baptist.

The lower part of the bell tower is a powerful two-story square, elongated along the street in the form of rectangular wing volumes. They are topped with through faceted turrets with tented roofs and petal-shaped domes. Above the eastern and western risalits of the square, there were turrets with five crosses, some of which have been lost.

The original architectural solution included a through arched passage from the street to the Epiphany Church through the first tier, which was bricked up during the Soviet era and reopened in the 1990s. Above it was a temple, accessed by a wide grand staircase in the northern wing.

Above the square rises the octagonal column of the bell tower, richly decorated with plastic elements, featuring two tiers of bells, cut through with large arched openings. The top is designed as a dome made of tin on a faceted drum.

The decor of the bell tower, skillfully laid out with red brick and white stone, combines modernized ancient Russian motifs with geometric forms from the turn of the 19th and 20th centuries. The design actively uses arched openings with keystone lintels, kokoshniks, half-columns with overlaps along the edges of the octagons, and arcature belts in various variations.
