Not far from Sao Beach in the south of the island, Phu Quoc's notorious old prison, built by the French in the late 1940s, contains a small museum that narrates (in English) the jail's gruesome history. Much of the site comprises mannequins of Vietnamese soldiers in chilling re-enactments, such as being forced to stand and starve in exposed, outdoor barbed-wire cages. A war memorial stands south of the prison, on the far side of the road.
