After the building was severely damaged in the Reichstag fire of February 1933, the Nazi Reichstag met in the nearby Kroll Opera House. Towards the end of the war the surviving, but heavily damaged "Reichstag" building was the object of numerous Soviet attacks because it was seen as a symbol of the Third Reich. They hoisted the Red Flag just in time for the Mayday celebrations of 1945. After the war, it was repaired and used as an exhibition hall, but major renovation and rebuilding were needed for the new German "Bundestag". Since 1999 the German "Bundestag" has used the former "Reichstag" as its permanent building. Its official address is "Platz der Republik 1".
