"Visiting Tuol Sleng Genocide Museum and the Killing Fields is a haunting, hallowed experience — Tuol Sleng, a former school-turned-interrogation center, displays rusty beds and torture devices that stand in stark contrast to the jasmine in its gardens, and the Killing Fields provide a sobering memorial to the victims; admission to both (including a guided tour) is about $20 USD and is an important, solemn part of understanding Cambodia’s past." - Matthew Kepnes
