The NBC Tower is an office tower on the Near North Side of Chicago, Illinois, United States 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.
The design, by Adrian D. Smith of Skidmore, Owings & Merrill, is considered one of the finest reproductions of the Art Deco style and similar to the GE Building in New York City. The tower is further enhanced by the use of limestone piers and recessed tinted glass with granite spandrels.
The building takes cues from the nearby landmark Tribune Tower with the use of flying buttresses. A 130 ft (40 m) broadcast tower and spire tops the skyscraper.
