Why Visit:
Tuol Sleng Genocide Museum is Cambodia’s most powerful memorial to the Khmer Rouge era, occupying the site of the notorious S-21 prison where an estimated 17,000 people were tortured and killed between 1975 and 1979. The museum preserves the original buildings, cells, and thousands of photographic records, as well as torture devices and survivor testimonies. Its exhibits are graphic and highly emotional, serving as a stark reminder of Cambodia’s recent history and the importance of justice and peacebuilding. A visit is essential for those seeking to understand the depth of Cambodian suffering—and resilience—during one of the 20th century’s darkest chapters.
