Galg, watervat, stenen doodskisten en verhoorlokalen.

It was formerly the Tuol Svay Prey High School, named after a royal ancestor of King Norodom Sihanouk. The five buildings of the school complex were converted in August 1975. Four months after the Khmer Rouge won the Cambodian Civil War,it became a prison and interrogation center. The Khmer Rouge renamed the complex "Security Prison 21" (S-21) and construction began to adapt the prison to the inmates: the buildings were enclosed in electrified barbed wire. The classrooms converted into tiny prison and torture chambers, and all windows were covered with iron bars and barbed wire to prevent escapes.

So the Tuol Sleng is a former Khmer Rouge detention and torture camp. Today it's a museum, a ghastly reminder of the dark days of the Khmer Rouge regime. Tuol Sleng means "Hill of the Poisonous Trees" or "Strychnine Hill".
Tuol Sleng was only one of at least 150 execution centers in the country, and as many as 20,000 prisoners there were later killed.

Upon arrival at the prison, prisoners were photographed and required to give detailed autobiographies, beginning with their childhood and ending with their arrest. After that, they were forced to strip to their underwear, and their possessions were confiscated.
The prisoners were then taken to their cells. Those taken to the smaller cells were shackled to the walls or the concrete floor


All the classrooms were transformed into prison cells and interrogation chambers. Each building has three floors at most. The bottom floor housed the smallest cells, each holding a single prisoner chained to the floor. Women were confined to the second floor. The third floor were mass prison cells, holding large groups chained to long iron bars.
The day in the prison began at 4:30 a.m. when prisoners were ordered to strip for inspection. The guards checked to see if the shackles were loose or if the prisoners had hidden objects they could use to commit suicide.

Ostensibly prisoners were brought here to be imprisoned and interrogated. The unspeakable torture that went on here meant that the prisoners would confess to anything. School boys confessed to being agents of the CIA, housewives made up stories about their neighbours... not even Communist higher-ups were immune from this treatment.

S-21 is in Tuol Svay Prey sub-district, south of the capital Phnom Penh. The graves of Tuol Sleng's last victims precede the visitor entering the complex. After paying the entrance fee, you can walk through by yourself, or get a guide to accompany you. We suggest you do the latter - Tuol Sleng is almost unremittingly grim, and you'll need someone to put all the death and pain in context.

De cellen in een lokaal

The horrible genius of the Khmer Rouge lay in their attention to detail. Prisoners were photographed and interrogated on their life details before being chained to their cells. This impersonal collection of data is presented to the visitor, room after room full of photographs of doomed men, women, and children, a glimpse of the estimated 20,000 prisoners who entered Tuol Sleng.

The prisoners were overwhelmingly Cambodian, although the prison did see its share of Americans, British, and Australians. The twisted ideology of the Khmer Rouge meant that anybody with an education, anybody who wasn't from around there, even anybody who wore glasses was suspect, and could (and often did) end up screaming their lives out in Tuol Sleng.

You'll also see a torture chamber, left in almost the same condition as they were found by the Vietnamese invaders who kicked the Khmer Rouge out in 1979. The torture devices are also present, with detailed explanations on how they were used.

The end result of these devices is also nearby - cases of skulls belonging to S-21's unfortunate victims. (Tuol Sleng's most grisly attraction, a "skull map" of Cambodia in 300-plus skulls, was dismantled in 2002. )

The Vietnamese found Tuol Sleng by following the stench of decay. When they arrived, they found only seven prisoners alive (just barely), and several other less fortunate folk chained to iron beds, only recently killed by the escaping Khmer Rouge.
