Charlottenburg-Wilmersdorf is the fourth borough of Berlin, formed in an administrative reform with effect from 1 January 2001, by merging the former boroughs of Charlottenburg and Wilmersdorf. Charlottenburg-Wilmersdorf covers the western city centre of Berlin and the adjacent affluent suburbs. It borders on the Mitte borough in the east, on Tempelhof-Schöneberg in the southeast, Steglitz-Zehlendorf in the south, Spandau in the west and on Reinickendorf in the north. The district includes the inner city localities of Charlottenburg, Wilmersdorf and Halensee.
After World War II and the city's division by the Berlin Wall, the area around Kurfürstendamm and Bahnhof Zoo was the centre of former West Berlin, with the Kaiser Wilhelm Memorial Church as its landmark. The Berlin Institute of Technology (Technische Universität Berlin), the Berlin University of the Arts (Universität der Künste), the Federal Institute for Risk Assessment (Bundesinstitut für Risikobewertung), the Deutsche Oper Berlin as well as Charlottenburg Palace and the Olympic Stadium are also located in Charlottenburg-Wilmersdorf.
