In the postwar years, new industrial and agricultural enterprises were put into operation and massive housing construction began. The lookalike five-story apartment blocks that remain today in Kirovsky, Chkalovsky, and other residential areas of Sverdlovsk sprang up in the 1960s, under the direction of Nikita Khrushchev's government. In 1977, Ipatiev House was demolished by order of Boris Yeltsin in accordance to a resolution from the Politburo in order to prevent it from being used as a rallying location for monarchists. Yeltsin later became the first President of Russia and represented the people at the funeral of the former Tsar in 1998. There was an anthrax outbreak in Sverdlovsk in April and May 1979, which was attributed to a release from the Sverdlovsk-19 military facility.
