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.
