The city of Irkutsk, founded in 1661, now belongs to the historical settlements of Russia. The historical center of the city is included in the UNESCO world heritage tentative list, and most Orthodox churches are located in this area. There are about 17 cathedrals in the city, most of which were destroyed or closed in the middle of the twentieth century, but now some of them have reopened after extensive reconstruction. And new images of temples win the hearts of people.
