The Reichstag (German: Reichstagsgebäude pronounced [??a?çsta?ksg??b??d?]; officially: Deutscher Bundestag -- Plenarbereich Reichstagsgebäude pronounced [ ?d??t?? ?b?nd?s?ta?k ?ple?na?rb?ra?ç ??a?çsta?ksg??b??d?]) is a historic edifice in Berlin, Germany, built 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. Following World War II, the building fell into disuse; the parliament of the German Democratic Republic (the Volkskammer) fulfilled in the Palast der Republik in East Berlin, while the parliament of the Federal Republic of Germany (the Bundestag) fulfilled in the Bundeshaus in Bonn.
The destroyed building was made secure against the elements and partly refurbished in the 1960s, but no attempt at full restoration was made until after German reunification on 3 October 1990, when it underwent a reconstruction led by architect Norman Foster.
