To accommodate the victims of purges that were important enough for the attention of the Khmer Rouge, a new detention center was planned in the building that was formerly known as Tuol Svay Prey High School,[5][6] named after a royal ancestor of King Norodom Sihanouk. The five buildings of the complex were converted in March or April 1976 into a prison and an interrogation center. Other buildings in town had already been used as prison S-21. The Khmer Rouge renamed the complex "Security Prison 21" (S-21) and construction began to adapt the prison for 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 and suicides.

Choeung Ek Mass graves containing 8,895 bodies were discovered at Choeung Ek after the fall of the Khmer Rouge regime. Many of the dead were former political prisoners who the Khmer Rouge kept in their Tuol Sleng detention center and in other Cambodian detention centers. Today, Choeung Ek is a memorial, marked by a Buddhist stupa. The stupa has acrylic glass sides and is filled with over 5,000 human skulls. Some lower levels are opened during the day so that the skulls can be seen directly. Many have been shattered or smashed in. Tourists are encouraged by the Cambodian government to visit Choeung Ek. Apart from the stupa, there are pits from which the bodies were exhumed. Human bones still litter the site.

According to legend, in 1372, a wealthy old lady named "Penh" lived on a small hill near the bank of the confluence of the four rivers. One day, when it was raining, Penh went down to the port to take a bath and saw a floating Koki tree in the river and she called the village to fish it from the water. She and the villagers took a piece of wood to scrape off the mud and in the hole of the Koki tree, there were four Buddha statues made of bronze, brass and one made of marble. Another statue was in the form of Vishnu with the hands holding a staff, a chain, a snail, and a lotus flower. Penh asked the villagers to help retrieve the Koki tree and retrieve the four treasures. Later, Penh assigned the villagers to build an artificial hill and build a small wooden temple on top of the hill to house the statues. She invited monks to bless the statues and the monks named the hermitage "Wat Phnom" which is known as to this day.
