Philadelphia possesses an exceptionally large number of places that have almost disappeared-from workshops and factories to sporting clubs and societies, synagogues, churches, theaters, and railroad lines. In Philadelphia: Finding the Hidden City, urban observers Nathaniel Popkin and Peter Woodall uncover the contemporary essence of one of America's oldest cities. Working with accomplished architectural photographer Joseph Elliott, they explore secret places in familiar locations, such as the Metropolitan Opera House on North Broad Street, the Divine Lorraine Hotel, Reading Railroad, Disston Saw Works in Tacony, and mysterious parts of City Hall.Much of the real Philadelphia is concealed behind facades. Philadelphia artfully reveals its urban secrets. Rather than a nostalgic elegy to loss and urban decline, Philadelphia exposes the city's vivid layers and living ruins. The authors connect Philadelphia's idiosyncratic history, culture, and people to develop an alternative theory of American urbanism, and place the city in American urban history. The journey here is as much visual as it is literary; Joseph Elliott's sumptuous photographs reveal the city's elemental beauty.
