The Tretyakov collection, handed over to Moscow in 1892, was later replenished through private collections and public procurement. The gallery presents all the main schools of Russian art: Old Russian icon painting, painting and sculpture of the 18th - first half of the 19th centuries, the work of the Wanderers and Miriskussniks, avant-garde artists and other masters of the 20th century. The oldest icon of the Virgin of Vladimir is stored in the church of St. Nicholas in Tolmachi.
