A memorial to the victims of one of the most horrific genocides in human history
This former orchard and Chinese graveyard is now the burial place for over 17,000 people who were murdered by the Khmer Rouge during the late 1970's; most were detainees at the S-21 prison in Phnom Penh. The site today is eerily quiet, with signs marking mass graves strewn across the sun-dappled paths and patchy grass. There's not much else to remind you of the atrocities committed here, so to ensure that you don't forget, the Cambodian government erected what is probably the most macabre stupa on the planet. The 17-story high monument is filled with over 5,000 human skulls, as well as other bones and clothing.
