The wharves and docks of William Penn's city that helped build a nation are gone lost to the onslaught of over 300 years of development. Yet the bygone streets and piers of Philadelphia's central waterfront were once part of the greatest trade center in the American colonies. Local historian Harry Kyriakodis chronicles the history of the city's original port district from Quaker settlers who first lived in caves along the Delaware and the devastating yellow fever epidemic of 1793 to its heyday as a maritime center and then the twentieth century that saw much of the historic riverfront razed. Join Kyriakodis as he strolls Front Street, Delaware Avenue, and Penn's Landing to rediscover the story of Philadelphia's lost waterfront.
