eventually resulted in greater maintenance costs. Yet it is here where the "Stalin's Empire" canon was largely developed. Bolshaya Kaluzhskaya (now Leninsky Prospect), a similar development of standard block-wide buildings east of Gorky Park All-Union Agricultural Exhibition (1939) In 1936, the annual Agricultural Exhibition was relocated to an empty field north of Moscow. By August 1, 1939, more than 250 pavilions were built on . A 1937 statue by Vera Mukhina, Worker and Kolkhoz Woman, atop the USSR pavilion of the Exposition Internationale des Arts et Techniques dans la Vie Moderne (1937) (Paris Expo of 1937), was rebuilt at the entrance gates. Pavilions were created in the national styles of Soviet republics and regions; a walk through the exhibition recreated a tour of the huge country. The central pavilion by Vladimir Schuko was based slightly on the abortive 1932 Palace of Soviets draft by Zholtovsky. Unlike the "national" buildings, it hasn't survived (central gates and major pavilions were rebuilt during the early 1950s). The surviving 1939 pavilions are the last and only example of Stalin's monumental propaganda in their original setting. Such propaganda pieces were not built to last (like Shchusev's War Trophy Hangar in Gorky Park); some were demolished during the de-Stalinization of 1956. Post-War (1944–1950) Post-war architecture, sometimes perceived as a uniform style, was fragmented into at least four vectors of development: Luxurious residential and office construction of complete regions such as the Moskovsky Prospekt in Leningrad and the Leninsky Prospekt in Moscow. Major infrastructure projects (Metro in Leningrad and Moscow, Volga-Don Canal). Rebuilding war damage of Kursk, Minsk, Kiev, Smolensk, Stalingrad, Voronezh, and hundreds of smaller towns. The effort for new, low-cost technologies to resolve the housing crises, evident since 1948 and the official state policy since 1951. Building of new cities: Novosibirsk, Kemerovo, Dzerzhinsk and elsewhere. Residential construction in post-war cities was segregated according to the ranks of tenants. No effort was made to conceal luxuries; sometimes they were evident, sometimes deliberately exaggerated (in contrast with Iofan's plain House on Embankment). Country residencies of Stalin's officials was on the top level; so was the 1945 House of Lions by Ivan Zholtovsky (House of Lions was designed by Nikolai Gaigarov and M.M. Dzisko of Zholtovsky Workshop. Zholtovsky supervised and promoted the project), a luxurious downtown residence for Red Army Marshals. 1947 Marshals Apartments by Lev Rudnev, on the same block, has a less extravagant exterior package.
