The third and sixth General Assembly sessions , in 1948 and 1951 , met in the Palais de Chaillot in Paris . Prior to the construction of the current complex , the UN was headquartered at a temporary location at the Sperry Corporation 's offices in Lake Success , New York , an eastern suburb of the city in Nassau County on Long Island , from 1946 to 1952 . The Security Council also held sessions on what was then the Bronx campus of Hunter College ( now the site of Lehman College ) from March to August 1946 . The UN also met at what is now the Queens Museum , built as the New York City Pavilion for the 1939 New York World 's Fair in Flushing Meadows - Corona Park . The General Assembly met at what had previously been the ice skating rink , and the Long Island Rail Road reopened the former World 's Fair station as United Nations station . After the UN moved to its new Manhattan headquarters , the building was remodeled and briefly used as a pavilion for the 1964 New York World 's Fair , after which it reverted to use as a skating rink until 2008 , when the entire building began a long - term renovation to create expanded museum facilities .
