The main portion of this walk is devoted to a thorough study of Rockefeller Center, and the sophisticated circulation systems
and public amenities in what was the first large-scale business complex in the United States. An innovative urban development
at the time it was built, Rockefeller Center was a model for future projects in the decades following its construction. A mixed-use
complex containing 13 buildings for commercial, retail and entertainment uses, the various structures were surrounded by open plazas
and gardens embellished with public works of art. Built between 1932 and 1940, the original buildings had a similar architectural
vocabulary that featured grey Indiana limestone, simple geometric forms, and bold facades with little decoration except for vertical lines
used to emphasize the height of the buildings. The central focus of the project is the former RCA building, a tower rising 70 stories above the Channel Gardens which serve as a monumental passage to the building from Fifth Avenue. Even today, the complex is still considered one of the best examples of urban architecture in the world built in the 20th century. In the 1960s, the Center was extended west across Sixth Avenue. The more recent additions to Rockefeller Center are somewhat bland, tall buildings set in open plazas that are characteristic of late modern architecture. A walk through midtown follows the tour of Rockefeller Center.
