UNESCO Report on Preah Vihear Temple Damage Released, Implies Thai Involvement

UNESCO and the International Council on Monuments and Sites (ICOMOS) officially released their joint mission report on the damage to Cambodia's Preah Vihear temple, a World Heritage site, on September 9, 2026, via the World Heritage Centre website. The expert team conducted an on-site inspection and assessment from March 1 to 6, 2026. The 104-page report compiles information on the history of the temple's damage, conservation and development plans, tourism management, challenges, emergency measures, restoration and conservation efforts, as well as fund assistance and related research. The report also includes numerous photographs illustrating the damage in various sections of the temple, showing impacts and destruction on walls and stone components, with some structural parts scattered on the ground. Certain areas have been cordoned off for safety to identify and clear unexploded ordnance. The report's publication follows UNESCO and ICOMOS's dispatch of expert officials to inspect and assess the temple's condition, at the invitation of Cambodia and under the coordination of relevant Cambodian authorities. According to the report, the mission assessed the severe damage caused by armed attacks in July and December 2025. These damages were found to have impacted the integrity, authenticity, and outstanding universal value of the Preah Vihear temple, a World Heritage site of Cambodia. The report records 142 damaged areas from the July attack and 420 areas damaged from the December 2025 attack, describing the scale of destruction from this recent conflict as "incomparable" to previous damages. The mission also clearly noted that "no area was spared from the impact." Not only the temple structures but also infrastructure and tourism equipment were damaged. More concerning is UNESCO-ICOMOS's assessment that the Preah Vihear temple is under "grave and imminent danger and requires urgent and significant conservation action." Regarding this report, Minister of Information Net Pheaktra stated: "Preah Vihear temple is not just a heritage of Cambodia, but a heritage of humanity. Protecting Preah Vihear temple is a duty that must be undertaken responsibly, respecting international law and without allowing armed conflict to continue destroying irreplaceable cultural heritage." During the World Heritage Committee meeting in July 2026, with support from the UNESCO Heritage Emergency Fund and other international partners, Cambodia implemented several emergency measures, including clearing cluster bombs and artillery fragments, preparing 3D documentation of the temple, protecting vulnerable structures, and collecting and recording architectural fragments in preparation for conservation and restoration. Preah Vihear temple was inscribed as a World Heritage site on July 7, 2008, making it 18 years ago.
