5 Most Dangerous Prisons in the World

3. Petak Island Prison, Russia

Petak Island Prison is located on an island in Novozero Lake. It houses some of the most dangerous convicts in Russia, but they do not fear danger from one another since their interaction is limited due to being confined in small two-man cells for 22.5 hours a day. The remaining 1.5 hours are spent in cages. Such adverse living conditions leave psychological bruises that severely deteriorate a person. The prisoners are not allowed any kind of education, are only allowed two short visits a year, are deprived of sanitary facilities, and are tortured beyond capacity.
