One of the most impressive architectural monuments of pre-revolutionary Irkutsk is the Kazan Cathedral, which astonishes with its beauty and unique style. Its construction was initiated by the famous Siberian entrepreneur and explorer Alexander Mikhailovich Sibiryakov. It is believed that the project of the cathedral was developed by architect Baron Heinrich von Rosen. The laying of the temple took place in a solemn atmosphere on July 27, 1885, and the consecration was led by Archbishop Benjamin. The construction site was chosen for its Craft Freedom, and funding was provided by numerous entrepreneurs, allowing the work to proceed without delays.

By 1892, the construction of the cathedral was completed, and on April 9, its consecration took place, conducted by Bishop Macarius. The church was built in the rare Neo-Byzantine style for Russia and amazed parishioners with its beauty. Local craftsmen created a true palace with exquisite architectural elements. Bright colors with a predominance of golden shades were used in the decoration, giving the temple a festive appearance.

During the Soviet era, the cathedral faced persecution but survived and in 1975 received the status of a state-protected object. Today, the temple is active again, although few outside Siberia know about it. If competitions were held for the most beautiful church, the Kazan Cathedral could surpass many famous temples.
