Rockefeller Center is a large complex consisting of 19 commercial buildings covering 22 acres between 48th Street and 51st Street in Midtown Manhattan, New York City. The 14 original Art Deco buildings, commissioned by the Rockefeller family, span the area between Fifth Avenue and Sixth Avenue, split by a large sunken square and a private street called Rockefeller Plaza. Later additions include 75 Rockefeller Plaza across 51st Street at the north end of Rockefeller Plaza, and four International Style buildings located on the west side of Sixth Avenue.
In 1928, the site's then-owner, Columbia University, leased the land to John D. Rockefeller Jr., who was the main person behind the complex's construction. Originally envisioned as the site for a new Metropolitan Opera building, the current Rockefeller Center came about after the Met could not afford to move to the proposed new building. Various plans were discussed before the current one was approved in 1932. Construction of Rockefeller Center started in 1931, and the first buildings opened in 1933. The core of the complex was completed by 1939.
The original center has several sections.
