Towards the end of World War II, on 12 March 1945, the opera was set alight by an American bombardment. The auditorium and stage were destroyed by flames, as well as almost the entire décor and props for more than 120 operas with around 150,000 costumes. The front section, which had been walled off as a precaution, however, remained intact including the foyer, with frescoes by Moritz von Schwind, the main stairways, the vestibule and the tea room. The State Opera was temporarily housed at the Theater an der Wien and at the Vienna Volksoper.
