Also known as Phu Quoc Prison, Phu Quoc POW Camp, Coconut Tree Prison…
The Phu Quoc Prison Historical Site, located in An Thoi, Phu Quoc Special Zone, An Giang Province, is one of the most significant wartime relics on Phu Quoc Island. It recreates the painful yet heroic chapters of Vietnam’s history during the resistance war.
Often referred to as the “Hell on Earth”, Phu Quoc Prison was notorious for its brutality, with more than 45 documented torture methods used by the U.S. and South Vietnam regime. In less than six years of operation (from June 1967 to March 1973), the prison held around 40,000 prisoners, mainly soldiers from liberation forces, along with political cadres and patriotic civilians. At peak capacity, each cell, measuring only 20m × 5m, was packed with 120–180 detainees. Over 4,000 prisoners were killed, while tens of thousands suffered permanent injuries.
The prison system was operated by approximately 2,000 military personnel, including naval, infantry, and air force units.
The entire compound covered 400 hectares, consisting of nearly 500 buildings divided into 12 zones, including 2 double zones and 10 single zones. Each zone contained four subdivisions—A, B, C, D—with each subdivision measuring 150m long and 50m wide. Every subdivision had 11 buildings, including 9 detention rooms. The structures were built with tin sheets and cement floors to prevent underground escape attempts. Guard towers operated around the clock, while 7–10 layers of barbed wire enclosed the entire area.
Despite extreme conditions, prisoners organized 45 escape attempts, including scaling fences, overpowering guards, and digging underground tunnels.
Remaining Structures and Exhibitions
Today, the site preserves several key structures and reconstructions, serving as an important destination for historical education:
- Battalion 8 Military Police Gate: Two brick pillars with reinforced steel cores mark the former entrance used by prison authorities.
- Prisoners’ Cemetery: Covering 20,427.8 m² on Hill 100, rebuilt after 1975. The centerpiece is a raised-fist monument symbolizing the indomitable spirit of Vietnamese revolutionaries.

- Exhibition House: Includes two rooms with 43 artifacts and over 100 archival photos, illustrating the prison’s structure, torture methods, and prisoners’ resistance activities.
