of narrow white pylons. The second round of the competition was held in 1959, and attended by Khrushchev himself. This time, all the entries followed the template established by Vlasov and Pavlov, with superficial differences. The new canon of Soviet state architecture, which first took tangible shape in the Soviet pavilion at the Expo 58, was now complete. Vlasov became the head of the new Palace of Soviets construction agency. Very little is known about its work, which ceased after Vlasov's death in 1962. The idea behind the Palace of the Soviets was laid to rest. Its intended role was taken over by the Palace of Congresses in the Moscow Kremlin, completed in 1961. The building replaced several heritage buildings, including the old neo-classical building of the State Armoury, and some of the back corpuses of the Great Kremlin Palace. This, and that the architecture of the projected building contrasted with the historic milieu resulted in quite an uproar, particularly after other historic buildings of the Kremlin, such as the Chudov and Ascension cloisters, had already been demolished during the Stalin era and laws, that were introduced by the mid-1950s, prohibited the demolishion of historic structures, making the construction in some ways illegal.
