UNESCO grants World Heritage status to Khmer Rouge atrocity sites – paving the way for other sites of conflict
- Written by Rachel Hughes, Associate Professor of Geography, The University of Melbourne
A series of atrocity sites of the Khmer Rouge regime in Cambodia have been formally entered onto the World Heritage list, as part of the 47th session of the World Heritage Committee.
This is not only important for Cambodia, but also raises important questions for atrocity sites in Australia.
Before this, the World Heritage list only recognised seven “sites of memory” associated with recent conflicts, which UNESCO defines as “events having occurred from the turn of the 20th century” under its criterion vi. These sat within a broader list of more than 950 cultural sites.
In recent years, experts have intensely debated the question of whether a site associated with recent conflict could, or should, be nominated and evaluated for World Heritage status. Some argue such listings would contradict the objectives of UNESCO and its spirit of peace, which was part of the specialised agency’s mandate after the destruction of two world wars.
Sites associated with recent conflicts can be divisive. For instance, when Japan nominated the Hiroshima Peace Memorial, both China and the United States objected and eventually disassociated from the decision. The US argued the nomination lacked “historical perspective” on the events that led to the bomb’s use. Meanwhile, China argued listing the property would not be conducive for peace as other Asian countries and peoples had suffered at the hands of the Japanese during WWII.
Heritage inscriptions risk reinforcing societal divisions if they conserve a particular memory in a one-sided way.
Nonetheless, the World Heritage Committee decided in 2023 to no longer preclude such sites for inscription. This was done partly in recognition of how these sites may “serve the peace-building mission of UNESCO”.
Shortly after, three listing were added: the ESMA Museum and Site of Memory, a former clandestine centre for detention, torture and extermination in Argentina; memorial sites of the Rwandan genocide at Nyamata, Murambi, Gisozi and Bisesero; and funerary and memory sites of the first world war in Belgium and France.
A number of legacy sites associated with Nelson Mandela’s human rights struggle in South Africa were also added last year.
Atrocities of the Khmer Rouge
The recently inscribed Cambodian Memorial Sites include prisons S-21 (now known as Tuol Sleng Genocide Museum) and M-13, as well as the execution site Choeung Ek.
These sites were nominated for their value in showing the development of extreme mass violence in relation to the security system of the Khmer Rouge in 1975–79. They also have value as places of memorialisation, peace and learning.
The Khmer Rouge developed its methods of disappearance, incarceration and torture of suspected “enemies” during the civil conflict of 1970–75. It established a system of local-level security centres in so-called “liberated” areas.
One of these centres was known as M-13, a small, well-hidden prison in the country’s rural southwest. A man named Kaing Guek Eav – also called Duch – was responsible for prisoners at M-13.
Shortly after the entire country fell to the Khmer Rouge in April 1975, Duch was assigned to lead the headquarters of the regime’s security system: a large detention and torture centre known as S-21.
Under his instruction, tens of thousands of people were detained in inhumane conditions, tortured and interrogated. Many detainees were later taken to the outskirts of the city to be brutally killed and buried in pits at a place called Choeung Ek.
The sites operated until early 1979, when the Khmer Rouge was forced from power.
The S-21 facility and the mass graves at Choeung Ek have long been memorialised as the Tuol Sleng Genocide Museum and the Choeung Ek Genocidal Centre.
However, the former M-13 site shows few visual clues to its prior use, and has only recently been investigated by an international team led by Cambodian archaeologist and museum director Hang Nisay. The site is on an island in a small river that forms the boundary between the Kampong Chhnang and Kampong Speu provinces.
Further research, site protection and memorialisation activities will now be supported, with help from locals.
From repression to reflection
The Cambodian memorial sites have been recognised as holding “outstanding universal value” for the way they evidence one of the 20th century’s worst atrocities, and are now places of memory.
In its nomination dossier for these sites, Cambodia drew on findings from the Khmer Rouge Tribunal to verify and link the conflict and the sites.
In 2010, the tribunal found Duch guilty of crimes against humanity and grave breaches of the Geneva Conventions. Duch was sentenced to 30 years in prison (which eventually turned into life imprisonment). He died in 2020.
While courts such as the International Criminal Court have previously examined the destruction of heritage as an international crime, drawing on legal findings to assert heritage status is an unusual inverse. It raises important questions about the legacies of former UN-supported tribunals and the ongoing implications of their findings.
The recent listings also raise questions for Australia, which has many sites of documented mass killing associated with colonisation and the frontier wars that lasted into the 20th century.
Might Australia nominate any of these atrocity sites in the future? And could other processes such as truth-telling, reparation and redress support (or be supported by) such nominations?
