Tuol Sleng Genocide Museum

This museum is housed in the former detention and interrogation centre of the Khmer Rouge, which operated in 1975–1979 in the city of Phnom Penh, the population of which had previously been evacuated in 1975. Over the course of four years, 15–20,000 people were imprisoned here, of whom 12 were alive by 1979. The museum consists of the authentic prison, its archive and a memorial.
