Pbs Learning Media: Underground Railroad

Black slaves fleeing their imprisonment in the South often sought the help of sympathetic Northerners while on their way to Canada. WLVT PBS 39 Tempo! investigates how the underground railroad traveled through an 18th Century house in Reading, PA. Under the house is a network of tunnels filled with broken pottery and other 19th Century artifacts. These tunnels, which once protected refugees, are now threatened by highway construction.
