Things that go bump in the clink.

Would you like to go to prison? No. How about a haunted prison? Hell no! How about a haunted prison at night with just a flashlight? Maybe …

Eastern State Penitentiary’s massive haunted house, Terror Behind the Walls presented by LUKOIL, will introduce an all-new attraction for the 2006 season, Night Watch. This section of the 177-year-old prison will be lit only by the flashlights in the visitors’ hands.

Visitors will be given flashlights before they enter the attraction (they may not bring their own), and broken into groups of two or four. They will be left to explore the space on their own. While there are some startling surprises waiting for them, it’s the raw, disturbing atmosphere of Eastern State Penitentiary that will make the experience unsettling.

“There is nothing as scary as Eastern State Penitentiary in the dark,” said Program Director Sean Kelley. “We realized that what scares us, the staff, is walking through the empty prison alone with a flashlight. It’s terrifying.”

Sounds pretty freakin’ scary considering the prison’s history.

Due to Eastern State’s ominous appearance, gloomy atmosphere and long history, it is a popular location for television shows and movies. The Sci Fi Channel’s Ghost Hunters and MTV’s Fear both explored the supernatural at Eastern State, while Terry Gilliam’s film Twelve Monkeys used it as the setting for a mental hospital.
