United Nations Secretariat Building in the context of "Wallace Harrison"

The headquarters of the United Nations (UN) is on 17 to 18 acres (6.9 to 7.3 ha) of grounds in the Turtle Bay neighborhood of Midtown Manhattan in New York City. It borders First Avenue to the west, 42nd Street to the south, 48th Street to the north, and the East River to the east. Completed in 1952, 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.

The United Nations General Assembly Building is part of the headquarters of the United Nations in the Turtle Bay neighborhood of Manhattan in New York City. It contains the main assembly hall of the United Nations General Assembly, the main deliberative, policymaking, and representative organ of the United Nations (UN). The building was designed by a group of architects led by Wallace Harrison. It is connected to the other buildings in the UN headquarters, including the Secretariat Building and the Dag Hammarskjöld Library. Although the building is physically within the United States, it is exempt from some local regulations because the site is under UN jurisdiction.

The General Assembly Building is a four-story structure measuring 380 by 160 ft (116 by 49 m), with concave walls to the west and east, as well as a concave roof with a dome. The building contains a lobby for journalists and the general public to the north, as well as a lobby for delegates to the south. The central portion of the General Assembly Building is the General Assembly Hall, which has a seating capacity of 1,800 and measures 165 ft (50 m) long, 115 ft (35 m) wide, and 75 ft (23 m) tall. Each delegation has six seats in the hall, which face south toward a rostrum and a paneled semicircular wall with booths. The building also contains other spaces, including a delegates' lounge and the president of the United Nations General Assembly's offices on the second floor; a meditation room on the ground floor; and various shops and conference rooms in the basement.

The Dag Hammarskjöld Library is a library on the grounds of the headquarters of the United Nations, located in the Turtle Bay/East Midtown neighborhood of Manhattan in New York City. It is connected to the Secretariat and Conference buildings through ground level and underground corridors. It is named after Dag Hammarskjöld, the second secretary-general of the United Nations. The library was founded in 1946, and the current library building was completed in 1961.

The library provides research and reference services to staff of the UN Secretariat as well as members of UN permanent missions. Additionally, the library is the main depository for United Nations documents and publications and maintains a selected collection of materials of the specialized agencies and United Nations affiliated bodies, as well as a collection of books, periodicals and other materials related to the organization's programs of activities. The library also produces a digital library of UN materials, an index to the proceedings and documentation of the major UN bodies, as well as providing research guides for finding UN-related material and information. The library also supports the network of UN libraries throughout the world by supporting collaborative information resource purchasing.

The East Side of Manhattan refers to the side of Manhattan which abuts the East River, and faces Brooklyn and Queens, all in New York City. Fifth Avenue, Central Park from 59th to 110th streets, and Broadway below 8th Street separate it from the West Side.

The major neighborhoods on the East Side include (from north to south) East Harlem, Yorkville, the Upper East Side, Turtle Bay, Murray Hill, Kips Bay, Gramercy, East Village, and the Lower East Side. The main north-south expressways servicing the East Side are the Franklin D. Roosevelt East River Drive and Harlem River Drive, which, for the majority of their length, are separated from the east shore of the island by the Manhattan Waterfront Greenway. The East Side is served by the IRT East Side Line subway, and by many bus lines.
