== Comcast Towers ==

The Comcast Center (2008), designed by Robert A.M. Stern Architects, rose 58 stories to become Philadelphia's tallest building, ending One Liberty Place's two-decade reign. The tower's design departs from postmodern historicism, employing a sleek glass curtain wall with subtle setbacks that create a tapered profile. The building's most notable feature—an LED screen in the lobby displaying commissioned video art—demonstrates integration of architecture and media appropriate to its telecommunications tenant. The tower's LEED Gold certification announced commitment to sustainable design that subsequent Philadelphia buildings would follow.<ref name="stern">{{cite book |last=Stern |first=Robert A.M. |title=Robert A.M.

Comcast Technology Center (2018), designed by Foster + Partners, surpassed its predecessor at 1,121 feet, making it the tallest building in Philadelphia and among the tallest in North America outside New York and Chicago. The tower's glass facade incorporates an innovative natural ventilation system, while its mixed-use program—offices, hotel, restaurants, and broadcast facilities—creates activity throughout the day. The Four Seasons Hotel occupies upper floors, its sky lobby providing public access to dramatic views. The building's technical sophistication and architectural refinement demonstrate Philadelphia's ability to attract global design talent for signature projects.<ref name="davidson"/>
