Despite such physical comforts as skylights, private exercise yards, central heating, and flush toilets—revolutionary for 1829—Eastern State Penitentiary in Philadelphia was a place of deprivation. Inmates were hooded whenever they were outside their cells; solitude, along with honest labor, was meant to turn them penitent. Among the ghosts said to roam the halls of Eastern State, which was abandoned in 1971, is the figure of an inmate who killed 27 men during an attempted prison break.
