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, United States. 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 US, it is exempt from some local regulations because the site is under UN jurisdiction.
The General Assembly Building is a four-story structure measuring , 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 long, wide, and 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 design process for the United Nations headquarters formally began in February 1947. The General Assembly Building was the third building to be constructed at the headquarters, after the Secretariat and Conference buildings. Construction of the General Assembly Building's steelwork began in February 1950, and the building was formally dedicated on October 10, 1952. The rapid enlargement of the United Nations prompted the UN to modify the hall's layout several times in the 1960s. The General Assembly Hall was closed for renovation from 1978 to 1979 to accommodate additional delegations. The building started to deteriorate in the 1980s due to a lack of funding, and UN officials considered renovating the complex by the late 1990s, but the project was deferred for several years. As part of a wide-ranging project that began in 2008, the General Assembly Building was renovated from 2013 to 2014.
Site
The General Assembly Building is part of the headquarters of the United Nations in the Turtle Bay neighborhood of Manhattan in New York City. It occupies a land lot bounded by First Avenue to the west, 42nd Street to the south, the East River to the east, and 48th Street to the north. Although it is physically within the United States, the underlying land is under the jurisdiction of the United Nations (UN). The site is technically extraterritorial through a treaty agreement with the US government, though it is not a territory governed by the UN. Most local, state, and federal laws still apply within the UN headquarters. Due to the site's extraterritorial status, the headquarters buildings are not New York City designated landmarks, since such a designation falls under the purview of the New York City Landmarks Preservation Commission.
The General Assembly Building occupies the center of the United Nations site, stretching roughly between 44th Street to the south and 45th Street to the north. The building is directly connected to the Conference Building (housing the Security Council) at its southeast, and it also indirectly connects with the United Nations Secretariat Building and the Dag Hammarskjöld Library to the south. The Japanese Peace Bell is just south of the building, and a grove of sycamore trees is planted to the side. On the western part of the site, along First Avenue, are the flags of the UN, its member states, and its observer states. Outside of the UN headquarters, Trump World Tower and the Japan Society are to the northwest, and the Millennium Hilton New York One UN Plaza hotel is to the southwest.
Historically, the site was part of a cove called Turtle Bay. The cove, located between what is now 45th and 48th Streets, was fed by a stream that ran from the present-day intersection of Second Avenue and 48th Street. A creek from the southern end of modern-day Central Park also drained into Turtle Bay. The first settlement on the site was a tobacco farm built in 1639. The site was developed with residences in the 19th century. Slaughterhouses operated on the eastern side of First Avenue for over a hundred years until the construction of the United Nations headquarters. The UN purchased the site in 1946 under the sole condition that it could never slaughter cattle on the land.
