Visit to Our Lady of Vladimir Church. Built originally out of wood in 1747, the actual stone building was inaugurated in 1768 and designed by the architect Pietro Antonio Trezzini with a surprising mix of the Baroque and Neoclassical styles. Situated in a densely populated area, this is one of the churches most often visited by the city’s inhabitants, and boasts five onion-shaped domes along with one separated belfry. During the communist rule in Russia it hosted an anti-religious library, though its religious functions were restored in 1989. One of its most famous visitors was Dostoyevsky, who frequently prayed at the church.
