The Reich Chancellery (German: Reichskanzlei) was the traditional name of the office of the Chancellor of Germany (then called Reichskanzler) in the period of the German Reich from 1878 to 1945. The Chancellery's seat, selected and prepared since 1875, was the former city palace of Prince Antoni Radziwiłł (1775–1833) on Wilhelmstraße in Berlin. Both the palace and a new Reich Chancellery building (completed in early 1939) were seriously damaged during World War II and subsequently demolished.
