The main building of Tretiakov Gallery itself is also an outstanding work of Moscow's new art style. In 1872, Trediakov built the first exhibition halls beside his apartment. In 1881, his private gallery was opened to the public for free. Tredyakov's collection is strictly selected, not a good work, and he resolutely refuses to buy it. As the reputation of the gallery grew, it was a great honor for some artists to enter the gallery with their works.
