The United Nations Office at Geneva (UNOG, ) in Geneva, Switzerland, is one of the four major offices of the United Nations where numerous different UN agencies have a joint presence. The main UNOG administrative offices are located inside the Palais des Nations complex, which was originally constructed for the League of Nations between 1929 and 1938. Besides United Nations administration, the Palais des Nations 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 Coordination of Humanitarian Affairs (OCHA) and the United Nations Economic Commission for Europe (ECE). The United Nations and its specialized agencies, programmes and funds may have other offices or functions hosted outside the Palais des Nations, normally in office spaces provided by the Swiss Government. UN specialised agencies and other UN entities with offices in Geneva hold bi-weekly briefings at the Palais des Nations, organized by the United Nations Information Service at Geneva. UNOG produces an annual report where it lists all major events and activities that happened through a year.
