It is located in the Palais des Nations building constructed for the League of Nations between 1929 and 1938 at Geneva in Switzerland, and expanded in the early 1950s and late 1960s. Besides United Nations administration, it also hosts the offices for a number of programmes and funds such as the United Nations Conference on Trade and Development (UNCTAD), the United Nations Office for the
