Since 1922, the sessions of the Riigikogu have taken place in the Toompea Castle, where a new building in an unusual Expressionist style was erected in the former courtyard of the medieval castle in 1920–1922. During the subsequent periods of Soviet occupation (1940–41), German occupation (1941–44), and the second Soviet occupation (1944–1991) the Riigikogu was disbanded. The castle and the building of the Riigikogu were used by the Supreme Soviet of the Estonian SSR during the second Soviet occupation.
