Phu Son prison (Trại Phú Sơn) is behind the Sai Gon- Con Dao hotel. The prison's claim to fame is its most notorious revolutionary prisoners, the likes of early revolutionary Le Hong Phuong, and later Le Duan, who succeeded Ho Chi Minh as the president of Vietnam at the end of the Vietnam War. Plaques listing the names of famous internees are next to each door.
