"Prison Islands" refers to islands that were historically used to house prisoners. These locations often isolated inmates from the mainland, making escape difficult. Notable examples include Alcatraz Island in the United States and Devil's Island in French Guiana, which were notorious for their harsh conditions and infamous inmates. Many of these islands have since been abandoned or repurposed. Today, some, like Alcatraz, serve as tourist attractions, offering insights into their historical significance. Others remain largely untouched, preserving the stories of those who were once confined there and the impact of incarceration on society.
