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.

United Nations Slavery Memorial, officially known as The Permanent Memorial at the United Nations in Honour of the Victims of Slavery and the Transatlantic Slave Trade, is an installation at the Headquarters of the United Nations in New York City intended as a permanent reminder of the long-lasting effects of slavery and the slave trade.The Slavery Memorial concept came from various resolutions adopted by the UN General Assembly including A/RES/62/122, A/RES/63/5, and the Durban Declaration.The memorial was designed by Haitian-American architect Rodney Leon, and unveiled on March 25, 2015. 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. The project was supported by the Permanent Memorial Trust Fund; the estimated cost of the project prior to its construction was 4.5 million dollars.

Waterside Generating Station was a power station in Manhattan, New York City that opened in 1901 and was one of the first power plants in the United States that generated electricity using steam turbines. Built by the New York Edison Company, the facility was located in the Murray Hill neighborhood on the east side of First Avenue between East 38th and 40th streets alongside the East River. The Waterside station also later served as a cogeneration facility and generated steam for the New York City steam system. The power plant was decommissioned by Con Edison in 2005 and sold to private developers as part of the East River Repowering Project, which increased the capacity of the East River Generating Station at East 14th Street to replace the steam and electric output of the Waterside Generating Station. After demolition of the Waterside plant, the site underwent environmental remediation and was rezoned to allow for residential and commercial development. As of 2023, the property has remained vacant land.

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 chapel has long been a popular site for wedding ceremonies, especially ones between couples of different religious or national backgrounds. Other events and conferences have been held at the chapel and in the church center as well.

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.

The Ford Foundation Center for Social Justice (also known as 321 East 42nd Street, 320 East 43rd Street, or the Ford Foundation Building) is a 12-story office building in East Midtown Manhattan in New York City. Designed by architect Kevin Roche and engineering partner John Dinkeloo in the late modernist style, the building was one of the first that Roche-Dinkeloo produced after they became heads of Eero Saarinen's firm. The building consists of a glass-and-steel cube held up by piers made of concrete and clad with Dakota granite. The main entrance is set along 43rd Street. A second entrance on 42nd Street leads to a large public atrium, the first such atrium in an office building in Manhattan. The atrium contains landscaping from Dan Kiley and includes plants, shrubs, trees, and vines. Most offices in the building are north and west of the atrium and are visible from other offices in the building. The building was commissioned for the Ford Foundation, then the largest private foundation in the United States, after Henry Heald became foundation president. The Ford Foundation Building was announced in 1963 and completed in 1968 on the former site of the Hospital for the Ruptured and Crippled. Between 2015 and 2018, the Ford Foundation Building underwent a major renovation and restoration project, and it was renamed the Ford Foundation Center for Social Justice. The Ford Foundation Building has been critically acclaimed for its design, both after its completion and after the renovation. The New York City Landmarks Preservation Commission designated the building and its atrium as city landmarks in 1997.
