Center City Tower was the working name of a formerly proposed skyscraper in downtown Philadelphia.
Designed and proposed by the firm now known as KlingStubbins (designers of Philadelphia's Penn Center and Bell Atlantic Tower), the building would have risen to a height of 1,050 feet (320 m) and 75 stories, making it the tallest building in The United States outside New York and Chicago, surpassing the height of the Bank of America Plaza in Atlanta.
Renderings depict it being sheathed in blue glass with studios/media center on the ground level.
The relative lack of a need for that much office space in Philadelphia ultimately doomed the proposal.
In addition, two new highrises - Residences at the Ritz and 1441 Chestnut have occupied and bifurcated the original plot.
