St. Charalampus Church, Orthodox church in Irkutsk, Russia

St. Charalampus Church, also called the Church of Michael the Archangel, stands at 5th Army Street 59 in central Irkutsk. The stone church replaced a wooden one in 1777–1779; its baroque forms were altered in the early 19th century with classicist rebuilding, likely after earthquakes. The 1879 fire damaged its tower and roof, and the dome and bell tower were rebuilt from 2005.

A wooden two-altar church was built in 1738 and consecrated on 24 January 1739. The stone church replaced it from 1777 to 1779 and was later called St. Michael the Archangel Church. The 1861 earthquake led to a renovation completed in 1868, and the 1879 fire damaged the tower and roof. Closed in the early 1930s, the church was returned to the diocese in 1998, and since 2005 the dome and tower have been rebuilt.

The church belongs to the Irkutsk Eparchy and serves as a gathering place for the local community. It remains an active center where people come to participate in religious services and observe traditional practices.

The church is part of guided walking tours that connect multiple religious sites in the city center. Visitors should prepare comfortable walking shoes, as the routes lead through downtown areas.

The merchant Ivan Khaminov, a major benefactor of Irkutsk, was buried on the church porch in 1884. In 1904 Alexander Kolchak married Sofia Omirova here, and priests blessed him before his expeditions down the Lena to the Arctic Ocean.
