Rockefeller Center is a complex of 19 commercial buildings covering 22 acres (89,000 m2) between 48th and 51st streets in New York City, United States. Built by the Rockefeller family, it is located in the center of Midtown Manhattan, spanning the area between Fifth Avenue and Sixth Avenue. It was declared a National Historic Landmark in 1987.
Rockefeller Center was named after John D. Rockefeller, Jr., who leased the space from Columbia University in 1928 and developed it from 1930. Rockefeller initially planned a syndicate to build an opera house for the Metropolitan Opera on the site, but changed his mind after the stock market crash of 1929 and the Metropolitan's continual delays to hold out for a more favorable lease, causing Rockefeller to move forward without them. Rockefeller stated "It was clear that there were only two courses open to me. One was to abandon the entire development. The other to go forward with it in the definite knowledge that I myself would have to build it and finance it alone." He took on the enormous project as the sole financier, on a 27-year lease (with the option for three 21-year renewals for a total of 87 years) for the site from Columbia; negotiating a line of credit with the Metropolitan Life Insurance Company and covering ongoing expenses through the sale of oil company stock. The initial cost of acquiring the space and razing some of the building and construction of new building was an estimated $250,000,000 dollars; a staggering sum in 1930.
