The United Nations Secretariat Building is a skyscraper within the headquarters of the United Nations in the Turtle Bay neighborhood of Manhattan in New York City. It contains the offices of the United Nations Secretariat, the executive organ of the United Nations (UN). The building, designed in the International Style, is 505 ft (154 m) tall with 39 above-ground stories. It was designed by a group of architects led by Wallace Harrison. Although the building is located within the United States, the site is under UN jurisdiction, so the building is exempt from some local regulations. The Secretariat Building is designed as a rectangular slab measuring 72 by 287 ft (22 by 87 m); it is oriented from north to south and is connected with other buildings in the UN headquarters. The wider western and eastern elevations of the facade are glass curtain walls, while the narrower northern and southern elevations are made of marble. The Secretariat Building contains 889,000 sq ft (82,600 m2) of space. The lowest stories contain press offices, staff rooms, and other functions. The Secretariat offices are placed on the upper stories, which were originally arranged in a modular layout. The building also contains various pieces of artwork. The building's style has inspired the construction of other glass curtain wall buildings in Manhattan. The design process for the United Nations headquarters formally began in February 1947, and a groundbreaking ceremony for the Secretariat Building occurred on September 14, 1948. Staff started moving into the building on August 21, 1950, and it was completed in June 1951. Within a decade, the Secretariat Building was overcrowded, prompting the UN to build additional office space in the area. The building started to deteriorate in the 1980s due to a lack of funding, which was worsened by the fact that it did not meet modern New York City building codes. UN officials considered renovating the building by the late 1990s, but the project was deferred for several years. The Secretariat Building was renovated starting in 2010, and it reopened in phases from July to December 2012.

The Church Center for the United Nations is a private building founded, owned, and operated by the United Methodist Church as an interfaith space housing the offices of various religions as well as several non-governmental organizations. It is at 777 United Nations Plaza in New York City, across the street from, but not part of, the United Nations Headquarters complex. The 12-story center is most known for its first-floor Chapel at the United Nations, which has a modernist design.

The United Nations is headquartered in Midtown Manhattan, New York City, United States, and the complex has served as the official headquarters of the United Nations since its completion in 1951. It is in the Turtle Bay neighborhood of Manhattan, on 17 to 18 acres (6.9 to 7.3 ha) of grounds overlooking the East River. Its borders are First Avenue on the west, East 42nd Street to the south, East 48th Street on the north, and the East River to the east. The complex consists of several structures, including the Secretariat, Conference, and General Assembly buildings and the Dag Hammarskjöld Library. The complex was designed by a board of architects led by Wallace Harrison and built by the architectural firm Harrison & Abramovitz, with final projects developed by Oscar Niemeyer and Le Corbusier. The term Turtle Bay is occasionally used as a metonym for the UN headquarters or for the United Nations as a whole.The headquarters holds the seats of the principal organs of the UN, including the General Assembly and the Security Council, but excluding the International Court of Justice, which is seated in The Hague. The United Nations has three additional subsidiary regional headquarters, or headquarters districts. These were opened in Geneva (Switzerland) in 1946, Vienna (Austria) in 1980, and Nairobi (Kenya) in 1996. These adjunct offices help represent UN interests, facilitate diplomatic activities, and enjoy certain extraterritorial privileges, but do not contain the seats of major organs. Although it is physically situated in New York City, the land occupied by the United Nations Headquarters and the spaces of buildings that it rents are under the sole administration of the United Nations and not the U.S. government. They are technically extraterritorial through a treaty agreement with the U.S. government. However, in exchange for local police, fire protection, and other services, the United Nations agrees to acknowledge most local, state, and federal laws.None of the United Nations' 15 specialized agencies (such as UNESCO) are located at the headquarters. However, some "autonomous subsidiary organs", such as UNICEF, have their headquarters at the UNHQ.

It includes three main elements: a large triangular sculpture with a map depicting the triangular slave trade; a prone human figure depicting those who were transported overseas enslaved; and a reflecting pool mean to honour the memory of those who died in slavery.
