Tuol Sleng Genocide Museum

Tuol Sleng Genocide Museum in Phnom Penh, Cambodia, was once a high school transformed into Security Prison 21 (S-21) by the Khmer Rouge regime in the late 1970s. It served as a brutal detention center where thousands of people accused of opposing the government were imprisoned, tortured, and often executed. Today, the museum preserves photographs, documents, and remains to educate visitors about this grim chapter in Cambodian history, fostering awareness and remembrance of the atrocities committed during the Khmer Rouge era.
