Designed by Kohn Pederson Fox, and completed in 1990, this 54-story, 1.3 million square foot office building is known as the crown jewel of downtown Philadelphia. One of the tallest buildings in Philadelphia, this Class-A office property is the center of the central business district and is more than 90% occupied by first-class tenants such as Goldman Sachs, Boston Consulting Group, Mellon Bank, JPMorgan Chase, Ballard Spahr and Willis Towers Watson among many others. The 52nd floor Pyramid Club is the premier private business club in the City of Philadelphia. Silverstein acquired the building in 2019.
