Regional Government Building (until 1991 - the House of Soviets) is a 24-storey high-rise building on Oktyabrskaya Square in Yekaterinburg. Initially it was used as the location of the Sverdlovsk Regional Committee of the CPSU. Since 1991, the building houses the Government of the Sverdlovsk Region. Until the collapse of the USSR, it was the highest building in the USSR for the regional committee of the CPSU. It bears the unofficial name "Tooth of Wisdom".
The "House of Soviets" construction began by order of B.N. Yeltsin for the regional committee of the CPSU in 1975. The design of the building was entrusted to Moscow architects from the "Mezentsev's TsNIIEP of culture, sports and management buildings". The building was finished in 1982.
