New York City, USA.
The United Nations (U.N.) Headquarters is located in New York City, United States. Nestled on an 18-acre complex in Manhattan, between East 42nd Street and East 48th Street, it sits on the banks of the East River.
Established after World War II, the U.N. was officially chartered in 1945 with the objective of fostering international cooperation, preventing conflicts, and promoting peace and security worldwide. The construction of its headquarters in New York was completed in 1952, becoming a center for diplomatic discourse and negotiation.
The U.N. complex includes several major buildings: the Secretariat building, which houses the U.N.’s administrative offices; the General Assembly building, where all 193 member nations convene; and the Dag Hammarskjöld Library, named after the second Secretary-General of the U.N.
Despite being in the U.S., the land occupied by the U.N. Headquarters is considered international territory. This unique status allows diplomats from around the world to engage freely in discussions and decision-making processes.
The U.N. also has major offices in Geneva, Vienna, and Nairobi. However, the headquarters in New York remains the heart of the U.N., serving as a global hub for international diplomacy and cooperation.
