Tould Sieng Prison, or S-21

On April 17, 1975, two weeks before the fall of Saigon in Vietnam, the radical Khmer Rouge defeated the American-backed army of Cambodian President Lon Noi and marched into Phnom Penh.
A social cleansing began: The goal was to create a pure, self-sustaining peasant society. Some 1.7 million urban and educated people lost their lives as a result of hunger, forced labor, disease, torture and execution.

Tould Sieng Prison, or S-21 was once a school. Today it is a museum of genocide. Its empty rooms and small stone cells reflect the horror of the past. Thousands of black and white photos hang in the hallways. These were taken by the prisoners when they came to Toul Sieng. More than 12,000 people died under torture or were taken to the Killing Fields.
During the 3 years, eight months and 20 days, millions of people died.

A side note: The educated people recognized the Khmer by the white skin, glasses and the lack of calluses on their hands.Read more
