1256 UNITED NATIONS - United Nations Office at Geneva

Apart from the Headquarters situated in New York City, the United Nations has three regional headquarters, opened in Geneva (Switzerland) in 1946, Vienna (Austria) in 1980, and Nairobi (Kenya) in 2011. These help represent UN interests, facilitate diplomatic activities, and enjoy certain extraterritorial privileges, but only the main headquarters in New York contains the seats of the principal organs of the UN.

All fifteen of the United Nations' specialized agencies are located outside New York. The United Nations Office at Geneva (UNOG) is located in the Palais des Nations building constructed in Ariana Park for the League of Nations between 1929 and 1938, and expanded in the early 1950s and late 1960s. An international architectural competition was opened in 1926, on which participated 377 projects, but the jury was unable to decide on a winner.

Ultimately, the five architects behind the leading entries were chosen to collaborate on a final design: Julien Flegenheimer of Switzerland, Camille Lefèvre and Henri-Paul Nénot of France, Carlo Broggi of Italy and József Vágó of Hungary. The Palace and its buildings constitute the second-largest building complex in Europe after Versailles.
