During the Soviet era, Red Square maintained its significance, becoming a focal point for the new state. Besides being the official address of the Soviet government, it was renowned as a showcase for military parades from 1919 onward. Lenin's Mausoleum would from 1924 onward be a part of the square complex, and also as the grandstand for important dignitaries in all national celebrations. In the 1930s, Kazan Cathedral and Iverskaya Chapel with the Resurrection Gates were demolished to make room for heavy military vehicles driving through the square (both were later rebuilt after the fall of the Soviet Union). There were plans to demolish Moscow's most recognized building, Saint Basil's Cathedral, as well to make way for a larger Red Square, as well as the State Historical Museum. The legend is that Lazar Kaganovich, Stalin's associate and director of the Moscow reconstruction plan, prepared a special model of Red Square, in which the cathedral could be removed, and brought it to Stalin to show how the cathedral was an obstacle for parades and traffic. But when he jerked the cathedral out of the model, Stalin objected with his rather famous quote: "Lazar! Put it back!". However, no documented evidence exists of this encounter.
