A visit to the Tuol Sleng Genocide Museum and Cheung Ek is essential for a first time visitor to Cambodia. During the Pol Pot regime, Tuol Sleng, formerly a high school was converted to a detention centre known as S21.

Continue to Cheung Ek which became the Khmer Rouge’s best known Killing Field, where the remains of almost 9,000 bodies have been excavated from mass graves. Today it is a memorial site for Cambodians and visitors from all over the world to pay their respects for those lost. During the Khmer Rouge years, thousands of Cambodians were tortured and imprisoned in detention centres around the country; the visit is a profoundly moving experience.
