Overview
Originally a high school, Tuol Sleng (S-21) became a secret prison from 1975-1979 where 14,000-17,000 people were detained, tortured, and killed under the Khmer Rouge. Now preserved as a museum, it displays prisoner photographs, torture instruments, and cells that vividly convey the brutality of the era. Together with the Killing Fields, it is essential for understanding Cambodia's darkest chapter. Korean audio guides are available. Admission USD 5 (+ USD 3 audio guide). In central Phnom Penh, about 10 minutes by tuk-tuk from the Royal Palace.
Travel Tips
It's emotionally heavy — go in a calm state of mind. Visiting with the Killing Fields the same day is efficient, but consider your emotional bandwidth.
