The Tuol Sleng Genocide Museum (Khmer: សារមន្ទីរឧក្រិដ្ឋកម្មប្រល័យពូជសាសន៍ទួលស្លែង) is a museum in Phnom Penh, the capital of Cambodia. The site is a former high school which was used as the notorious Security Prison 21 (S-21) by the Khmer Rouge regime from its rise to power in 1975 to its fall in 1979. Tuol Sleng (Khmer [tuəl slaeŋ]) means "Hill of the Poisonous Trees" or "Strychnine Hill". Tuol Sleng was only one of at least 150 execution centers in the country,[1] and as many as 20,000 prisoners there were killed.
