The S21 Tuol Sleng Genocide Museum or just S21 as it was referred to under the Khmer Rouge Regime is housed in the buildings of a former school in Phnom Penh.
During the Khmer Rouge Regime the school was turned into a prison for people labelled as enemies of the regime.
At that time anybody of any age, male or female could find themselves imprisoned here, it just took one accusation to have you transported to a place where almost nobody left alive.
For those that did find themselves leaving Tuol Sleng, chances were that they were on their way to be executed.
Please be aware that there are images of scenes of torture inside some of the former cells and the site has a very sobering atmosphere. That being said in many ways S21 is a must see just like the Killing Fields it’s essential to understand some of the horrors this country faced during the Khmer Rouge years.
There are lots of buses filled with tourists and the narrow streets surrounding the site make parking slightly difficult at times, that being said, if you do have your own motorbike then there is some parking inside the site.
