Khmer Rouge Prison S21 - 1

Prison S21 (Genocide Museum)

The Museum is a former high school which was used as the notorious Security Prison 21 by the Khmer Rouge regime from 1975 to 1979. The school was converted into a prison and interrogation center in August 1975 by the Regime. The buildings were enclosed in electrified barbed wire, the classrooms were converted into tiny prison cells and torture chambers, and all windows were covered with iron bars and barbed wire to prevent escapes. From 1975 to 1979, an estimated 17,000 people were imprisoned and later killed at Choeung Ek Killing Fields. The buildings are preserved as they were left when the Khmer Rouge were driven out in 1979.

The Killing Fields

For the first year of Prison S21’s existence, corpses were buried near the prison. However, by the end of 1976, they ran out of burial spaces, they transported the prisoners and their families to Choeung Ek extermination centre for execution. Choeung Ek Killing Fields is the largest mass grave of victims of the Khmer Rouge. 8,895 bodies were discovered at Choeung Ek after the fall of the Khmer Rouge regime.

Definitely worth visiting. I highly recommend paying the few extra dollars for a tour guide at the S21 prison and getting the audio guide at the Killing Fields to enrich your overall experience.

It’s worth doing this trip to see what happened. The video in the coach was good and clearly explains the history of the rise and fall of Pol Pot.

 Reviewed by Morgan F on 14 July 2016

The tour itself was very organized, comfortable bus and video onboard was good. Overall Very interesting experience, also one I wont forget. It is very confronting but glad I learnt about the history.

It was just what we needed. Picked up from hotel in air conditioned bus.. It is nice to take some of the hassle out of travelling when you have been organising so much and just be part of a tour.. The whole thing ran like clockwork.

A good tour and well worth the cost. The visit to Tuol Sleng was very informative, as was the documentary shown to and from the venues. The visit to the Killing Fields was also very moving. The benefit of this tour is that you get to visit these key sites and gain knowledge without the queues or the dusty drive in a tuk tuk.

Really good trip. Well paced without over doing it. Excellent value

Reviewed by MVIC on 12 March 2016

Great trip for independent travelers. The audio guides at both destinations were excellent and everyone was able to move around the sites at their own pace. The video shown on the bus was very informative.
