The State Tretyakov Gallery (, Gosudarstvennaya Tretyâkovskaya Galereya; abbreviated ГТГ, GTG) is an art gallery in Moscow, Russia, which is considered the foremost depository of Russian fine art in the world. The gallery's history starts in 1856 when the Moscow merchant Pavel Mikhailovich Tretyakov acquired works by Russian artists of his day with the aim of creating a collection, which might later grow into a museum of national art. In 1892, Tretyakov presented his already famous collection of approximately 2,000 works (1,362 paintings, 526 drawings, and 9 sculptures) to the Russian nation. The museum attracted 894,374 visitors in 2020 (down 68 percent from 2019), due to the COVID-19 pandemic. It was 13th on the list of most-visited art museums in the world in 2020. 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. In 1977 the Gallery kept a significant part of the George Costakis collection. In May 2012, the Tretyakov Art Gallery played host to the prestigious FIDE World Chess Championship between Viswanathan Anand and Boris Gelfand as the organizers felt the event would promote both chess and art at the same time. History Pavel Tretyakov started collecting art in the middle of 1850. The founding year of the Tretyakov Gallery is considered to be 1856, when Tretyakov purchased two paintings of Russian artists: Temptation by Nikolay Shilder and Skirmish with Finnish Smugglers by Vasily Khudyakov, although earlier, in 1854–1855, he had bought 11 drawings and nine pictures by Dutch Old Masters. In 1867 the Moscow City Gallery of Pavel and Sergei Tretyakov was opened. The gallery's collection consisted of 1,276 paintings, 471 sculptures and 10 drawings by Russian artists, as well as 84 paintings by foreign masters. In August 1892 Tretyakov presented his art gallery to the city of Moscow as a gift. In the collection at this time, there were 1,287 paintings and 518 graphic works of the Russian school, 75 paintings and eight drawings of European schools, 15 sculptures and a collection of
