United Nations
Headquarters
New York City, New York, U.S.
The General Assembly selected New York City as the site for the headquarters of the UN, construction began on 14 September 1948 and the facility was completed on 9 October 1952. Its site—like UN headquarters buildings in Geneva, Vienna, and Nairobi—is designated as international territory. The Norwegian Foreign Minister, Trygve Lie, was elected as the first UN Secretary-General.
