Rockefeller Center is a complex of 19 commercial buildings covering 22 acres between 48th and 51st Streets in New York. Built by the Rockefeller family, it is located in the center of Midtown Manhattan, spanning between Fifth Avenue and Seventh Avenue. It is the largest privately held complex of its kind in the world, and an international symbol of commerce and capitalism.

Radio City Music Hall

The nation's largest indoor theater, Radio City Music Hall, is located in the complex. One of the complex's first and most important tenants was the Radio Corporation of America, hence the original names "Radio City" and "Radio City Music Hall."

Art

Rockefeller Center contains, amongst many other corporate tenants, the New York headquarters of the world's biggest auction house by revenue, Christies. The Center represents a turning point in the history of architectural sculpture: it's among the last major building projects in the United States to incorporate a program of integrated public art. Sculptor Lee Lawrie contributed the largest number of individual pieces, fourteen, including the statue of Atlas facing Fifth Avenue, and the conspicuous friezes above the main entrance to the RCA Building.

A large number of other artists contributed work here, including Carl Milles, Hildreth Meiere, Isamu Noguchi, Margaret Bourke-White, Dean Cornwell, and Leo Friedlander. The aesthetic quality of this work varies considerably and some of its allegorical content is enigmatic.

Flags

At street level, the plaza has about 200 flagpoles. At varying intervals, the flags of United Nations member countries, the flags of United States states and territories, or various decorative and seasonal flags are flown; during U.S. holidays, every flagpole carries the Stars and Stripes.
