The Chancellor's Office (Chancellery) (in German, Bundeskanzleramt, or more commonly Kanzleramt) is the office of the Chancellor, the head of the German federal government (Bundesregierung). The chief of the Chancellery (Chef des Bundeskanzleramtes) holds the rank of either a state secretary (Staatssekretär) or a federal minister (Bundesminister). The chief's primary function is to assist the Chancellor in coordinating the activities of the Federal Government, and may be compared to the White House Chief of Staff. The current chief of the Chancellery is Thomas de Maizière.
The Chancellery is also the name of the building that houses the personal offices of the Chancellor and the Chancellery staff.
The German Chancellery was established in 1871 as the Imperial Chancellery (Reichskanzlei), and originally had its seat in the Radziwill Palace (also known as Reichskanzlerpalais), built by Anton Radziwill in Wilhelmstraße 77 in Berlin. In 1938–39, the New Chancellery (Neue Reichskanzlei), designed by Albert Speer, was built; it was located at 6 Voßstraße and occupied the entire northern side of the Voßstraße between Wilhelmplatz (to the east) and Hermann-Göring-Straße (to the west). It was damaged during World War II and later demolished by Soviet occupation forces.
After the war, Bonn became seat of the West German government and the Chancellery (now known as the Bundeskanzleramt — Chancellor's Office) moved into Palais Schaumburg until a new Chancellery building was completed in 1976. The new West German Chancellery building was a black structure completed in the International Style, in an unassuming example of modernism.
In the summer of 1999, as part of the German government's move to Berlin, the Chancellery was temporarily housed in the former GDR State Council building (Staatsratsgebäude) in eastern Berlin as the new Chancellery building was not yet finished at the time.
The current Chancellery building (opened in the spring of 2001) was designed by Charlotte Frank and Axel Schultes and was built by the Spanish Acciona from concrete and glass in an essentially postmodern style, though some elements of modernist style are evident. Occupying 12,000 square meters (129,166 square feet), it is also one of the largest government headquarters buildings in the world. By comparison, the new Chancellery building is eight times the size of the White House.. Because of its distinctive but controversial architecture, journalists, tourist guides and some locals refer to the buildings as Kohllosseum (as a mix of collosseum and former chancellor Helmut Kohl under whom it was built), Waschmaschine (laundry machine; because of the round-shaped windows and its cubic form), or Elefantenklo (elephant loo).
Access for the general public is only possible on particular days during the year. Since 1999, the German government has welcomed the general public for one weekend per year to visit its buildings. This usually takes place in August and follows a German tradition called Tag der offenen Tür ("Day of the open door"), during which many institutions such as museums or other establishments are open for visitors (free of charge).
Directors of the Chancellery attend Cabinet meetings. They may also sit as members of the Cabinet if they are also given the position of Minister for Special Affairs (Minister für besondere Aufgaben), similar to that of Minister without Portfolio in some other countries. They are often incorrectly called "Kanzleramtsminister" (chancellery minister).
