Why visit
United Nations Headquarters occupies an eighteen-acre East River site acquired through John D. Rockefeller Jr.'s donation. Wallace Harrison led an international design team including Oscar Niemeyer and Le Corbusier; construction began in 1949 and the principal modernist complex was completed in 1952.
What to see
Four main elements define the composition: the 39-story glass-and-marble Secretariat slab, the low Conference Building, the curved General Assembly Building and the later Dag Hammarskjöld Library. Their sharply different forms separate administration, debate and public assembly while creating a collective architectural image for the organization.
Plan your visit
Meeting chambers, interpretation booths, artworks and gifts from member states fill the interior, and gardens line the river edge. Guided access can include the General Assembly Hall and Security Council Chamber when meetings permit, revealing the headquarters as a working diplomatic institution rather than a static monument.
