The Headquarters of the United Nations is the official headquarters of the United Nations since 1952. It is located in Turtle Bay district of Manhattan, overlooking the East River.

The complex includes; the Secretariat building (a 154 m (505 ft) tall skyscraper), the domed General Assembly building, the Dag Hammarskjöld Library (main depository for United Nations documents and publications), as well as the Conference and Visitors Center.

Although it is situated in New York City, the land occupied by the United Nations Headquarters and the spaces of buildings that it rents are under the sole administration of the United Nations and not the U.S. government. They are technically extraterritorial through a treaty agreement with the U.S. government. However, in exchange for local police, fire protection and other services, the United Nations agrees to acknowledge most local, state, and federal laws.


  • The 193 flags of the U.N. member states, located outside the building, are arranged in alphabetical order.
  • The United Nations has three subsidiary headquarters. These are in Geneva (Switzerland), Vienna (Austria), and Nairobi (Kenya). These adjunct offices help represent UN interests, facilitate diplomatic activities, and enjoy certain extraterritorial privileges, but only the main headquarters in New York City contains the seats of the principal organs of the UN, including the General Assembly and Security Council.
