text: World War II During World War II, air raids on Mannheim completely destroyed the city centre. Mannheim was heavily damaged during aerial bombing by the Royal Air Force (RAF) and the United States Army Air Forces (USAAF). Allied bombing raids razed the city centre of Mannheim at night-time area bombing, killing thousands of civilians. In the meantime, 2,262 of Mannheim's Jews were sent to Nazi concentration camps. Some sources state that the first deliberate strategic bombing of the war occurred at Mannheim during a Royal Air Force night raid on 16 December 1940. Today around one third of the city consists of buildings from before 1950.
  In late March 1945, the Allied ground advance into Germany reached Mannheim, which was potentially well-defended by German forces. However, the German forces abandoned the city and the U.S. 44th Infantry Division entered unopposed on 29 March 1945. There was later a large American military occupation presence in the Mannheim area with up to 10 barracks. The first one shut down in 2007 and the last was closed in 2013 (see United States military installations below).
  1950s to 1980s
  Rebuilding of the city began industriously. Mannheim Palace and the water tower (Wasserturm) eventually were rebuilt and the National Theatre was replaced by a new building at a new location. At the old location, there is a monument to Friedrich Schiller and the Zum Zwischen-Akt pub. The housing shortage led to the development of many new residential areas.
