Welcome to the headquarters of the UN, a worldwide organization overseeing international law, international security and human rights. While the soaring, Le Corbusier–designed Secretariat building is off-limits, one-hour guided tours do take in the General Assembly, where the annual convocation of member nations takes place every fall, as well as exhibitions about the UN's work and artworks given by member states.

To the north of the 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. The UN visitors’ entrance is at 46th St.
