Eastern State Penitentiary
Haunted attraction · Philadelphia · Pennsylvania
Philadelphia's crumbling 1829 penitentiary (one of the first true prisons in the world, abandoned in 1971) turns its cellblocks into Halloween Nights each fall: five haunted houses and an outdoor scare zone staffed by 200-plus performers, running select nights from mid-September through Halloween.
