In 1917, the building of Smolny Institute was chosen by Vladimir Lenin as Bolshevik headquarters during the October Revolution. It was Lenin's residence for several months, until the national government was moved to the Moscow Kremlin in March 1918. After that, the Smolny became the headquarters of the local Communist Party apparat, effectively the city hall. In 1927, a monument to Lenin was erected in front of the building, designed by the sculptor Vasily Kozlov and the architects Vladimir Shchuko and Vladimir Gelfreikh.
