Wissahickon Park

One of the most heavily industrialized creeks in America, the Wissahickon Creek and its impressive valley were home to dozens of mills and factories throughout the 18th and 19th centuries and now is a national Natural Landmark and one of the most unique places in the City of Philadelphia. Now known as Wissahickon Park, part of Philadelphia's Fairmount Park System, it has been a favorite subject of artists and writers like Edgar Allen Poe and John Greenleaf Whittier, who visited the rocky hillsides frequently for relaxation and inspiration.
