Mysteries of the Abandoned: Hidden America

Get chills in a bleak communications hub that housed a California cult, then eye a secret US Navy arsenal in Florida. Check into a decaying Ohio inn at the crossroads of history and tread lightly near a medieval contraption in a New Hampshire field.

A company town produces weapons that transform the Wild West, a building complex revolutionizes communications on this world and beyond, an old mine bears the scars of a deadly labor conflict, and a forest hides the remains of a socialite's mansion.

Visit strange structures in New York where Nazis helped launch the US Space Race, then see a New Orleans amusement park where joy turned to despair. Explore the remains of Idaho's first penitentiary and a Great Lakes industrial disaster site.

A research facility spawns new technology with earth-shattering implications; a coastal haven for African Americans changes the nation; a forgotten fortress fights off a Nazi submarine; a staunch building stands firm on San Francisco's darkest day.
