Wilhelmstrasse (German: Wilhelmstraße, see ß[1]) is a major thoroughfare in the central Mitte and Kreuzberg districts of Berlin, Germany. Until 1945, it was recognised as the centre of the government, first of the Kingdom of Prussia, later of the unified German Reich, housing in particular the Reich Chancellery and the Foreign Office. The street's name was thus also frequently used as a metonym for overall German governmental administration: much as the term "Whitehall" is often used to signify the British governmental administration as a whole. In English, "the Wilhelmstrasse" usually referred to the German Foreign Office.[2]
