Eastern State Penitentiary
Philadelphia, US
Once the world’s most expensive prison, the Eastern State
Penitentiary housed 1,700 inmates in its heyday – including Al
Capone – and was the first of its kind to introduce extreme
solitary confinement. Manifestations of former prisoners have been
wreaking havoc here since the 40s, leading to the site being
abandoned in 1971 – but ghosts tours are still available.
