The United Nations Headquarters in New York City

The United Nations (UN) is an international organization that facilitates co-operation between the world's countries on a wide variety of topics. This travel topic will cover the variety of interesting UN headquarters and sights all over the globe.

Headquarters

• 1 UN Headquarters New York, 1st Ave at 46th St, New York City, USA. The UN HQ sits on an 18-acre site between 42nd and 48th Streets, and between First Avenue and the East River. It is noted for its gardens and outdoor sculptures. There is a charge for the tours of the General Assembly and Secretariat but you can visit the Visitor's Lobby for free (although you do have to pass through a security checkpoint). There are two levels to the lobby area which includes a gallery, a gift shop, and a bookshop. If just visiting the lobby, don't join any queues once you're in the lobby—just find your way around. There is little in the way of signs to tell you where you can go—this is the UN: well-meaning but not well organized. Free; guided tours $11.50 adults, $8.50 seniors, $7.50 students, $6.50 children (6-14). 

• 2 Palais des Nations (UN Office at Geneva), 14 Avenue de la Paix, Geneva, Switzerland, ☏ +41 22-917 48 96, visit-gva@unog.ch. Open daily Apr-Oct 10AM-noon and 2PM-4PM; Jul-Aug 10AM-5PM; the rest of the year M-F 10AM-noon and 2PM-4PM (except over the Christmas period). Originally built to house the League of Nations, the Palais is worth visiting just to take in the magnificent Assembly Hall, in addition to the large collection of public art, the library, and the landscaped grounds. It is the second-largest UN Headquarters in the world. 12CHF each for adults. (groups of 20 adults or more qualify for a 20% discount; private tour of 1-14 adults 127.50CHF; 10CHF each for students, senior citizens, and disabled persons; 4CHF for schoolchildren; free for children under six years old).

• 4 UN Office at Nairobi (UN Complex Gigiri), United Nations Ave, Nairobi, Kenya, ☏ 254 -20-762 2034NOCC, un.tours@unon.org.
