Eastern State Penitentiary

Visitors walk through a corridor during the Halloween haunted house Terror Behind the Walls, at Eastern State Penitentiary in Philadelphia. The penitentiary took in its first inmate in 1829, closed in 1971 and reopened as a museum in 1994. The haunted house is scheduled to run through Nov. 9.

Haunted Prison in Philadelphia


An abandoned prison would seem creepy enough around Halloween. Now add blood-curdling screams and gruesome characters who can reach out and grab you.

That's the formula for "Terror Behind the Walls," the signature scarefest at historic Eastern State Penitentiary in Philadelphia, which is billed as the nation's largest haunted house outside an amusement park and staged for several weeks each fall at one of the city's most unusual tourist sites.
