Until March 10, the Royal Ontario Museum in Toronto is featuring an exhibition called Observance and Memorial: Photographs from S-21, Cambodia. This exhibition presents 103 prints developed from negatives left in the S-21 prison in Phnom Penh, Cambodia.
During the Cambodian genocide, from 1975 to 1979, Khmer Rouge dictator Pol Pot relocated many Cambodians into the countryside for forced labor in horrific conditions. These conditions and executions caused the death of one-fourth of the Cambodian population. S-21 was estimated to have had approximately 17,000 prisoners during this period; there are seven known survivors. The images of this exhibition are presented courtesy of the Tuol Sleng Genocide Museum and Photo Archive Group.
