The NBC Tower is an office tower on the Near North Side of Chicago, Illinois located at 454 North Columbus Drive (455 North Cityfront Plaza is also used as a vanity address for the building) in downtown Chicago's Magnificent Mile area. Completed in 1989, the 37-story building reaches a height of 627 feet (191 m). NBC's Chicago offices, studios, and owned-and-operated station WMAQ-TV are located here. The design, by Adrian D. Smith of Skidmore, Owings & Merrill, is considered one of the finest reproductions of the Art Deco style. (wikipedia.org)
