Occupying 17 to 18 acres in Turtle Bay, Midtown Manhattan, the United Nations headquarters is an International Style complex completed in 1952 that houses the seats of the UN's principal organs, including the General Assembly and Security Council. Designed by a board of architects led by Wallace Harrison and built by Harrison & Abramovitz, with final projects developed by Oscar Niemeyer and Le Corbusier, the compound comprises several structures: the Secretariat, Conference, and General Assembly buildings, and the Dag Hammarskjöld Library. Though situated on American soil, the grounds enjoy extraterritorial status through treaty agreement with the U.S. government, though the UN acknowledges most local, state, and federal laws in exchange for municipal services. The complex remains the primary seat of UN operations, distinct from the organization's additional regional headquarters in Geneva, Vienna, and Nairobi.
