Top 10 Infamous Prisons in the World

1. ADX Florence – USA

The Administrative Maximum Facility (ADX) prison is a super-max prison for the most dangerous criminals in America. Located in Colorado, the prison was opened in 1994 in response to several security breaches in other prisons of the country. One of the notorious features of the prison is the lack of human interaction. The prisoners are completely isolated from the guards and other inmates. Even the availability of light is limited. The loneliness leads some to madness and suicide. A former warden called the prison a ‘cleaner version of Hell’.
