The United Nations Secretariat Building is a 154 m (505 ft) tall skyscraper and the centerpiece of the headquarters of the United Nations, located in the Turtle Bay area of Manhattan, in New York City. The lot where the building stands is considered United Nations territory, although remains part of the United States.[3]


It has 39 stories and was completed in 1952.[4] The building was designed by the Brazilian architect Oscar Niemeyer and the Swiss-French architect Le Corbusier. This building is connected to the Conference Building to the north that houses the General Assembly, the Security Council, among others, and a library building to the south.

The building houses the administerial functions of the UN, including day-to-day duties such as finance and translation, and the offices of ambassadors and delegates.

As part of the UN complex, the building is subject to an agreement between the United Nations and its host country, the United States.[5]

The UN Secretariat Building was recently renovated, starting in May of 2010, and reopened via phased reoccupancy with the first occupants moving in July of 2012.[6]

The building style has inspired some notable copies, including the Headquarters of South Lanarkshire Council in Hamilton, Scotland - known locally as the "County Buildings".

On October 29, 2012 the basement of the UN complex was flooded due to the Hurricane Sandy, leading to a three day closure and the relocation of several offices.[7]
