Choeung Ek, a former orchard and Chinese cemetery about 17 kilometers south of Phnom Penh, is the most famous of the so-called Killing Fields where the Khmer Khmer regime executed approximately 17,000 people between 1975 and 1979. Mass graves with 8,895 bodies were discovered here after the fall of the dictatorship, many of the dead were former inmates of the Tuol-Sleng Prison.
Today, Choeung Ek is a memorial, marked by a Buddhist stupa. The stupa has acrylic glass walls and is filled with more than 5,000 human skulls. Some of the lower floors are open during the day so that the dead heads can be viewed directly.
The current government of Cambodia encourages the tourists to visit the site. In addition to the stupa, there are also pits from which the bodies were exhumed. The film The Killing Fields is a dramatized account of the events that took place in Choeung Ek.
