Comcast Center

Comcast Center, also known as the Comcast Tower, is a skyscraper in Center City, Philadelphia, Pennsylvania, United States. The 58-story, 297-meter tower is the second-tallest building in Philadelphia and the state of Pennsylvania, as well as the twenty-third tallest building in the United States. Originally called One Pennsylvania Plaza when the building was first announced in 2001, the Comcast Center went through two redesigns before construction began in 2005. Comcast Center was designed by Robert A.M. Stern Architects for Liberty Property Trust.

At the beginning of 2005, the final redesign and its new name—the Comcast Center—was unveiled. The building is named after its lead tenant, cable company Comcast, which makes the skyscraper its corporate headquarters. Leasing 1,094,212 square feet, Comcast takes up 89 percent of the building.
