Rockefeller Center is a large complex consisting of 19 commercial buildings covering 22 acres between 48th and 51st Streets, facing Fifth Avenue in Midtown Manhattan, New York City. The 14 original Art Deco buildings, commissioned by the Rockefeller family, span the area between Fifth and Sixth Avenues, split by a large sunken square and a private street called Rockefeller Plaza. Five International Style buildings, built later, are located on the west side of Sixth Avenue and at the north end of Rockefeller Plaza.
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.
