From river to skyline and stoop to stoop, Philadelphia has been re-formed and re-shaped throughout its history. Its transformation from bustling port to workshop of the world to World Heritage City and hub for education, medicine, and entrepreneurship has had a profound impact on both its built and natural environments and the lives of those who call it home. Images of the city drawn from 300 years of prints, photographs, documents, and maps in the Special Collections and Research Departments of the Parkway Central Library reveal the planned and unplanned changes that have affected Philadelphia's landscape, its buildings, and its inhabitants.
