The Genocide Museum, Tuil Sleng, in Phnom Penh is an austere memorial to the memory of the 20,000 prisoners exterminated here by the Khmer Rouge between 1975 and 1979. Once an unknown high school, it was turned it into the infamous Security Prison 21…the S-21. In the Khmer language Tuil Sleng means Hill of the Poisonous Trees or Strychnine Hill. Two Cambodians bide their time outside the Genocide Museum while skulls from the horrors can be viewed through the window behind them.
