Welcome to the United Nations Headquarters in New York City!
The Headquarters of the World Organization is located on an 18-acre site on the East side of Manhattan. It is an international zone belonging to all Member States. The United Nations has its own security force, fire department and postal administration. Visitors from all over the world often like to send postcards back home with United Nations stamps - these stamps can only be mailed from the United Nations.
The Headquarters consist of four main buildings: the General Assembly building, the Conference Building, the 39-floor Secretariat building, and the Dag Hammarskjold Library, which was added in 1961. The complex was designed by an international team of 11 architects, led by Wallace K. Harrison from the United States.
