The Reichstag building (; officially: Plenarbereich Reichstagsgebäude) is a historical 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 it was 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.
