Choeung Ek, one of the Khmer Rouge's brutal Killing Fields across Cambodia during their genocidal rule.
From 1975 - 1978, nearly twenty thousand men, women, and children "prisoners" were brought by bus from their torturous time at the S21 site to be executed. Soldiers blasted propoganda music to mask the sound of nightly murders. Sunken pits reveal mass graves, where bones and rags still rise to the surface. An audio tour shares personal testimonies of beatings, starvation, rape, and even babies beaten against trees. The Khmer Rouge believed in fully decimating generations of people, though they were fellow Cambodians; to cut down a tree, you have to pull it from the roots. Today, a pagoda-like memorial displays the skulls of the victims.
