The property consists of three locations that reflect the human rights abuses of the Khmer Rouge regime in Cambodia from 1971 to 1979. The three component parts represent the widespread violence during this period: the former M-13 prison (early repression), the Tuol Sleng Genocide Museum (former S-21 prison), and the Choeung Ek Genocidal Center (former execution site of S-21). These places have been preserved and memorialized since the regime’s fall. The Tuol Sleng Museum maintains extensive archives and collections related to this period, mainly documented by the Extraordinary Chambers in the Courts of Cambodia (ECCC).
