The Holy Cross Cathedral in Irkutsk was completed in 1747 AD. The church is famous for its unique exterior design, where the facades are richly decorated, along with simple geometric shapes and flowers that match the complex design. Judging by the decoration, you can see the influence of local Russian folk art, and this church is the only one in Siberia with interiors from the 17th century. The church is surrounded by a beautiful beautiful garden that includes impressive ice sculptures in the winter, while in the summer there are many green herbs and picturesque trees.
