City West (formerly known as Neuer Westen ("New West") or Zooviertel ("Zoo Quarter")) is an area in the western part of central Berlin. It is one of Berlin's main commercial areas, and was the commercial centre of former West Berlin when the city was divided by the Berlin Wall.
City West started developing in the Wilhelmine era from about 1895 onwards as a commercial and entertainment centre of the German Empire's capital, in addition to the historical centre in Mitte. At that time, Charlottenburg, Schöneberg and Wilmersdorf still were towns in their own right, rivalling with Berlin for locational advantages. The KaDeWe opened in 1907 competed with the Wertheim and Tietz department stores on Leipziger Straße in Mitte. Likewise, the Theater des Westens opened in 1896 or the Romanisches Café from 1916 were newly established cultural institutions.
After World War II and the division of Germany the area around the Zoologischer Garten railway station developed to the West Berlin city centre in the Cold War era. The process was reinforced by the building of the Berlin Wall in 1961, followed by the opening of the Europa-Center high-rise on Breitscheidplatz two years later. After the German reunification in 1990, the central administrative functions of reunified Berlin are today again located in Mitte. Nevertheless, City West has struggled to maintain its status as "second centre" and one of the main commercial areas of the city beside Alexanderplatz, Friedrichstraße and Potsdamer Platz, stressing its distinct boulevard character and the exclusive range of items. Recent building projects like the Zoofenster document these efforts.
