The One Washington Square (formerly Penn Mutual Towers) are established landmarks centered within Philadelphia's historic and business districts. The award-winning three-building complex, with towers constructed in 1914, 1930 and 1972, is one of the city's most highly regarded corporate addresses hosting a roster of prestigious firms. The Penn Mutual Towers overlook Independence Square and offer extraordinary views of the city from nearly every floor. The Philadelphia waterfront and some of the nation's most significant monuments add to the appeal of this important location. Impressive polished marble floors, commanding columns and intricate plaster ceilings above the walnut concierge and security station are striking indications of the quality of the complex. First class renovations throughout both towers offer comfortable, attractive and flexible space. Expansive window lines further enhance the setting, allowing natural light in offices and spectacular views.
