Choeung Ek — Uncover the Killing Fields Secrets
You are a lead investigator for the newly established Cambodian Documentation Center in Phnom Penh, 1980, tasked with reconstructing evidence of the Khmer Rouge regime between 1975 and 19
Dive into the corridors of time where Pol Pot and the Khmer Rouge orchestrated one of the most terrifying genocides of the 20th century.
The story that haunts this land
Phnom Penh still bears the scars of Khmer Rouge occupation that began April 17, 1975. Your route starts at the Independence Monument, this 20-meter tower inspired by Angkor Wat and inaugurated November 9, 1958 to celebrate Cambodia's independence from France in 1953. Damaged by an explosion in 1993 during the civil war, this monument witnesses the decades of violence that followed. Independence Park surrounding it, covering 4 hectares, was the scene of public gatherings before becoming a forced deportation site under Pol Pot.
Your investigation leads to Wat Phnom, Buddhist temple founded in 1373 by Lady Penh on a 27-meter artificial hill. This site houses relics of King Ponhea Yat, founder of Phnom Penh in the 15th century, but was desecrated by the Khmer Rouge who installed a reeducation center there. Monks were executed or forced to flee, transforming this sacred place into a symbol of systematic cultural destruction led by Pol Pot's regime between 1975 and 1979.
The Royal Palace, built in 1813 under King Ang Duong and covering 1.2 km², tells another facet of this tragedy. Official residence of Khmer kings, it was occupied by the Khmer Rouge in 1975 before being partially damaged. The Silver Pagoda, with its 5,000 silver tiles weighing 5 tons, was looted and its treasures scattered. Norodom Sihanouk, dethroned king then manipulated by Pol Pot, lived the humiliation of seeing his own palace transformed into a golden prison.
Cambodia's National Archives, French colonial building from 1920 on Street 13, preserve over 50,000 ancient manuscripts including some documenting Khmer Rouge crimes. This place, 800 meters from Independence Monument, houses moving testimonies from survivors and deportation lists to labor camps. Khieu Samphan, Khmer Rouge president born in 1931, had thousands of documents destroyed there to erase evidence of the genocide that cost nearly 2 million Cambodian lives.
Your archivist mission ends at Sisowath Quay, 4-km promenade along the Mekong named after King Sisowath. This area, witness to American bombings in 1973 during the Vietnam War, was transformed into a deportation port to the countryside. Developed in the 1990s after the regime's fall, it now symbolizes Phnom Penh's renaissance. You leave with visceral understanding of this period when Cambodian history plunged into horror, and the crucial importance of preserving memory of these crimes against humanity.
