Postmodern Philly: BNY Mellon Center
Philadelphia has a number of interesting buildings featuring postmodern architecture, the most outstanding of which are One and Two Liberty Place.
But this one ain't bad either. The 54-floor, 792 foot tall skyscraper was completed in 1990 and was originally named Mellon Bank Center. The current name represents the 2007 merger of Bank of New York with Mellon Financial Corporation, rebranded as BNY Mellon. Kohn Pederson Fox were the architects.
Apparently one Comcast building isn't enough for Philadelphia; you can see the new Comcast Innovation and Technology Center rising behind BNY Mellon. It will be 1,121 feet tall, exceeding the height of the mouldy old (2008) Comcast Center by 142 feet. That will make it the eight-tallest building in the United States and the tallest building in the country outside of New York and Chicago.
