The coconut tree prison which is also known as “Phu Quoc Prison” is located in An Thoi Village, Phu Quoc. The name “coconut tree” originated from the Indochina War; when French colony was dominating Vietnam and the resistant war against French becomes very strong. At this time, the prison had four areas named “A”, “B”, “C” and “D”; which was believed to keep over 14,000 prisoners. However, when the Indochina War finished, most of the prisoners returned to their families according to the Geneva Accords.
