The United Nations Building is the seat of the United Nations Headquarters, located on the east side of Manhattan in New York City, United States, and is an international territory, so it is accessible as long as a national of a Member State has a passport. From the United Nations Headquarters building, you can overlook the East River. The towering United Nations Headquarters building, like a huge book, is set on a thick square base. Sculptures celebrating peace and opposing war are dotted around the building.
