Top 10 Infamous Prisons in the World

4. Carandiru Penitentiary – Brazil

Located in Brazil, Carandiru is one of the worst, brutal, most dangerous and infamous prisons in history. Built in 1920 and operational from 1956 to 2002, it was once the largest prison in South America. It was venue of one of the worst prison massacres ever, when 102 inmates were shot dead following a riot in 1992. Over the 46 years of its history, 1300 inmates have lost their lives. The prison acquired quite notoriety for human rights violations. Carandiru was closed and demolished in 2002 as the result of a wide campaign led by Amnesty International. A part of the prison is now a museum.
