The State Tretyakov Gallery is an art gallery in Moscow, Russia, the foremost depository of Russian fine art in the world. The façade of the gallery building was designed by the painter Viktor Vasnetsov in a peculiar Russian fairy-tale style. It was built in 1902–04 to the south from the Moscow Kremlin. During the 20th century, the gallery expanded to several neighboring buildings, including the 17th-century church of St. Nicholas in Tolmachi. The collection contains more than 130,000 exhibits, ranging from Theotokos of Vladimir and Andrei Rublev's Trinity to the monumental Composition VII by Wassily Kandinsky and the Black Square by Kazimir Malevich.
