Welcome to the headquarters of the UN, a worldwide organization overseeing international law, international security and human rights. While the Le Corbusier–designed Secretariat building is off-limits, one-hour guided tours do cover the restored General Assembly Hall, Security Council Chamber, Trusteeship Council Chamber and Economic and Social Council (ECOSOC) Chamber, as well as exhibitions about the UN's work and artworks given by member states. Weekday tours must be booked online and photo ID is required to enter the site.
Free walk-in access to the visitor center only is permitted on weekends (enter at 43rd Street). To the north of the UN complex, which technically stands on international territory, is a serene park featuring Henry Moore’s Reclining Figure, as well as several other peace-themed sculptures.
