The Kazan Church in Irkutsk is located in the suburb of Rabochy, in the Right Bank district. It is truly a beautiful architectural structure and one of the main attractions of the city. The church was consecrated in 1892 by Bishop Makary. The funds for its construction were provided by Alexander Sibiryakov, a renowned explorer and entrepreneur. Significant donations were also made by merchants and gold industry figures Dmitry Demidov and Alexander Trapeznikov, as well as other patrons, who raised about 20,000 rubles. Parishioners contributed an additional 1,500 rubles. The church was built by Ural architects in the Russian-Byzantine style. Many craftsmen worked on its construction and decoration, but only a few names have survived to this day. The Kazan Icon of Mother of God Church functioned until 1936. During the Soviet period, the building changed hands multiple times, and each owner altered the interior at their discretion, leading to a loss of authenticity and gradual decay. In 1975, the church was included in the list of state-protected sites.

In the 1980s, the people's deputies of Irkutsk decided to restore this religious monument. Restoration work began in 1988 under the guidance of L.I. Gurova, the chief architect of the Irkutsk restoration workshops. The restoration took a long time and was funded by voluntary donations. By 1994, the main part of the restoration was completed, and the church reopened its doors to the faithful. In 2011, a 12-meter iconostasis weighing 70 tons, made of red-coffee granite brought from India, was installed. Ural serpentine was used in the columns. The main bell was cast in the city of Tutayev at the Shuvalov factory using ancient technologies.
