The Museum Island is a building ensemble consisting of five museums in the northern part of the Spreeinsel in the historic center of Berlin. It is one of the most important sights in the German capital and one of the most important museum complexes in Europe.

The Museum Island consists of the Old Museum, the New Museum, the Old National Gallery, the Bode Museum and the Pergamon Museum. Since the reunification of Germany, it has been renovated and expanded as part of the Museum Island master plan. On July 12, 2019, the James Simon Gallery opened as a new visitor center.

The Reichstag building (in short: Reichstag; officially: plenary area Reichstag building; unofficially also Bundestag or Wallot-Bau) on the Republic Square in Berlin has been the seat of the German Bundestag since 1999. The building was erected between 1884 and 1894 in Neo-Renaissance style according to plans by the architect Paul Wallot in the Tiergarten district on the left bank of the Spree. It housed both the Reichstag of the German Empire and that of the Weimar Republic. Initially, the Federal Council of the Empire also met there. After severe damage from the Reichstag fire of 1933 and World War II, the building was restored in a modernized form in the 1960s. From 1995 to 1999, the Reichstag was fundamentally redesigned by Norman Foster for permanent use as a parliament building, which was decided in 1991. The German Bundestag meets here. A landmark in the cityscape is the accessible glass dome above the plenary hall based on an idea by Gottfried Böhm.
