Two sites connected to the events of the 1970s are preserved as memorials and open to visitors. Tuol Sleng, in the middle of Phnom Penh, occupies a former secondary school and keeps its classrooms, records and photographic archive largely as they were found; it has been a museum since 1980. Choeung Ek lies about fifteen kilometres south, a quiet field of hollows with a memorial stupa at its centre, built in 1988. Both are visited with an audio guide, and both are managed as places of record rather than as attractions.
Highlights
- Tuol Sleng - preserved classrooms, the photographic archive and the documentation rooms.
- Choeung Ek - the field, the marked hollows and the memorial stupa.
- The audio guide - the narrated route used at both sites, in several languages.
- The memorial grounds - trees, ponds and marked paths kept as they are.
When to go
November to February for dry, cooler weather; both are open year-round. Go early - Choeung Ek is exposed with almost no shade, and by midday the heat makes the walk hard. Half a day covers both with the tuk-tuk ride between them. Allow silence at Choeung Ek; the audio guide runs about ninety minutes.
Good to know
The subject is what it is, and neither site softens it - this is not a stop to fit between other sights, and most people are finished with sightseeing for the day afterwards. Both publish rules on conduct and photography; follow them. Not suitable for children. Tuk-tuk drivers wait outside and the return trip is worth agreeing in advance. There is little shade and no proper cafe at Choeung Ek.
