Introduction
Phnom Penh is a city carrying enormous historical weight — the Khmer Rouge emptied it completely in 1975, forcing the entire population into the countryside, and then subjected the country to four years of genocide. Understanding this history is essential to understanding modern Cambodia. But Phnom Penh is also a rapidly developing, vibrant city with excellent food and a resilient, warm population.

Essential Historical Sites
Tuol Sleng Genocide Museum (S-21)
The most important museum in Cambodia. A former high school converted by the Khmer Rouge into the Security Prison 21 (S-21) from 1975–1979. Of the 17,000 people imprisoned here, only 7 survived.
The photographs of prisoners, the original cells, and the testimony of survivors make this one of the world’s most powerful museums. Allow 2–3 hours. Audio guide recommended.
Entry: $5. Not suitable for children under 12.
Killing Fields (Choeung Ek)
15km from the city center. Mass burial site where prisoners from S-21 were executed. The memorial stupa contains skulls of victims. The audio guide (included with entry) personalizes individual stories with extraordinary sensitivity.
Entry: $6 including audio guide. 30 minutes by tuk-tuk from Phnom Penh.
Note: Both S-21 and Choeung Ek are emotionally demanding. Visiting both in one day is difficult. Allow time for reflection.
