This modern glass and concrete structure, completed in 1961, is the Kremlin's most recent edifice. It was built during the halcyon days of the Khruschev administration to host Communist Party congresses and was executed in appropriately magnificent style. The palace's most prominent feature was its huge auditorium (6000 seats), the stage of which was surmounted by a monumental bas-relief head of Lenin surrounded by gilded rays. Today the palace is used for performances by the Kremlin Ballet Company, and the once familiar relief of Lenin is gone.
