The Palace of the Soviets (Russian: Дворец Советов, romanized: Dvorets Sovetov) was a project to construct a political convention center in Moscow on the site of the demolished Cathedral of Christ the Saviour. The main function of the palace was to house sessions of the Supreme Soviet in its 130-metre (430 ft) wide and 100-metre (330 ft) tall grand hall seating over 20,000 people. If built, the 416-metre (1,365 ft) tall palace would have become the world's tallest structure, with an internal volume surpassing the combined volumes of the six tallest American skyscrapers. This was especially important to the Soviet state for propaganda purposes.
Boris Iofan's victory in a series of four architectural competitions held between 1931 and 1933 signaled a sharp turn in Soviet architecture, from radical modernism to the monumental historicism that would come to characterize Stalinist architecture. The definitive design by Iofan, Vladimir Shchuko and Vladimir Helfreich was conceived in 1933–1934 and took its final shape in 1937. The staggered stack of ribbed cylinders crowned with a 100-metre (330 ft) statue of Vladimir Lenin blended Art Deco and Neoclassical influences with contemporary American skyscraper technology.
