Given momentum by these public renamings, the process of de-Stalinization peaked in 1961 during the 22nd Congress of the CPSU. Two climactic acts of de-Stalinization marked the meetings: first, on 31 October 1961, Stalin's body was moved from Lenin's Mausoleum in Red Square to a location near the Kremlin wall;[15] second, on 11 November 1961, the "hero city" Stalingrad was renamed Volgograd.[16]
