For a truly harrowing experience, take a nighttime flashlight tour of the abandoned Eastern State Penitentiary. It’s believed that inmates were driven insane by solitary confinement, torture and disease while the prison was in operation from 1829-1971. It has since been left in a state of “preserved ruin,” making for a seriously bone-chilling experience. Imagine being led out of your isolated cell for the very last time as you walk down Death Row, and get a true taste of imprisonment in the underground isolation cells under Cellblock 14. While there, you may notice that some prisoners were never able to escape the fortress-like penitentiary … even in the afterlife.
