Cambodia has one of the darkest histories known to mankind. While Khmer Rouge reigned over the country between 1975 and 1979, nearly 3 million Cambodians – roughly 25% of the country’s entire population – were wiped off the planet through execution, disease, or starvation. Today, the Cambodian government preserves the sites in which the bodies of the dead are buried as a monument to both the dead and survivors of this dark time in history. Choeung Ek is the largest killing field in Cambodia, and hundreds of thousands of visitors – foreign and local, alike – come to the site to learn about the past and pay their respects to the dead.
