A tour guide and driver pick up you at the lobby of hotel and transfer to visit Tuol Sleng Genocidal Museum, the memorial site of the S-21 interrogation and detention center of the Khmer Rouge regime and located in the heart of Phnom Penh. It preserves a tragic period in history with the aim to encourage visitors to be messengers of peace. Tuol Sleng Genocide Museum is the memorial site of “Security Office 21” (S-21) of Democratic Kampuchea (also known as the Khmer Rouge regime) and located in what was then the abandoned city of Phnom Penh, whose citizens had been evacuated on 17 April 1975. S-21 served as the central hub of a vast prison system throughout the country and was used throughout the period as a secret facility for the detention, interrogation, torture and extermination of those deemed “political enemies” of the regime.

After that, we travel about 15km toward southwest of Phnom Penh we will arrive at Choeung Ek. The memorial at Choeung Ek just outside Phnom Penh was an orchard! And a Chinese cemetery prior to 1975. During the Khmer Rouge regime, it became one of the killing fields the site of the brutal executions of more than 17,000 individuals, most of whom first suffered through torture and deprivation in Toul Sleng Prison. Choeung Ek is now a group of mass graves and a memorial stupa containing thousands of skulls.
