The church on the banks of the Telminka River was laid on June 9, 1814, and consecrated on August 20, 1816. A detailed record of this event has been preserved in the altar on a wooden eight-pointed cross. In the interiors of Orthodox churches, secular paintings are rarely found, but here on the outer wall of the choir, nine panels with landscapes are depicted. The true miracle was the chimes that played twelve musical pieces. It created the impression that they were performed by two archangels standing in niches on either side of the choir. At the right moment, they raised the gilded pipes, and a 'harmonious' chant sounded. On the second tier of the bell tower, details of this mechanical musical instrument, reminiscent of music boxes, are still preserved. The church was built by Joakim Ivanovich Shorin, and the chimes were created by master Klimov. Both were exiles working at the Telma factory. Documents testify that the inspirer of the construction of the 'harmonious temple' was Ignaty Ivanovich Sokolovsky, the director of the local factory from 1808 to 1820.

The Kazan church in the village of Telma near Baikal, north of Irkutsk, is a true phenomenon. It is not only the only rotunda church discovered in Siberia but also features unique architecture. Among rotunda churches, it is the only one with five domes, with four small domes located at the corners of the rectangle along the main axis of the church. The bell tower has an oval shape, which is a rarity.

The Diocesan records contain information about the builders and clergy of the church, as well as its property, but the name of the project author is not mentioned. Only the name of the initiator of the construction, the director of the cloth factory under which the church was built, is known. The author's name remains a mystery, although there are suggestions regarding the authorship of O. Bove. The main argument in favor of this version is the side loggias that surround the rotunda, similar to those in the Church of Archangel Michael in the Arkhangelsk estate and the Pokrov Church in Pekhra-Pokrovsk, designed by Bove. However, similar solutions can also be found in the works of N. Lvov and V. Bazhenov. The oval bell tower resembles one of Bazhenov's unrealized projects. It is hard to imagine anyone other than Bazhenov daring to position the domes as they are in the Kazan church. Another detail is the Maltese crosses above the windows of the second tier of the bell tower and rotunda, as well as their ribbon under the cornice of the rotunda. Bazhenov was a member of the Maltese Order, which may explain the choice of location for construction away from the capitals.

The author's name remains a hypothesis, but regardless of which version is correct, the Kazan church in the village of Telma occupies an important place in the history of domestic architecture.
