What city does Bundestag and Reichstag building have in common?
Reichstag building The Reichstag (German: "Reichstagsgebäude" ] ; officially: "Deutscher Bundestag - Plenarbereich Reichstagsgebäude" ] ) is a historic edifice in Berlin, Germany, constructed to house the Imperial Diet (German: "Reichstag"), of the German Empire. It was opened in 1894 and housed the Diet until 1933, when it was severely damaged after being set on fire. After World War II, the building fell into disuse; the parliament of the German Democratic Republic (the "Volkskammer") met in the "Palast der Republik" in East Berlin, while the parliament of the Federal Republic of Germany (the "Bundestag") met in the "Bundeshaus" in Bonn.
