Description Only the VIP political prisoners got their own personal torture room like this one to die in. Blood has permanently stained the floor and the mat on the bed. In 1976, the Khmer Rouge changed Tuol Svay Pray High School, Phnom Penh, Cambodia, into the S-21 torture, interrogation and execution center. Of the 14,000 people who entered, only seven survived. Khmer Rouge recorded interrogations and created an astonishing photographic archive of almost 6,000 S-21 prisoner portraits. Most were sent to the killing fields. Today, S-21 Prison is known as the Tuol Sleng Museum of Genocide. There is a lot more where this came from. Take a look at my gallery.
