Angkor Archaeological Park

Active Project

Siem Reap, Cambodia

Site History and Significance

Once the seat of the Khmer Empire, which ruled a large portion of mainland Southeast Asia between the ninth and fifteenth centuries AD, Angkor reached its peak in the twelfth century before entering a long period of decline. In the sixteenth century, only Angkor Wat was still in use; the dozens of Hindu and Buddhist temple complexes and hundreds of smaller structures had been swallowed by the jungle. Documented and partially restored in the 1850s by European explorers, Angkor’s temples garnered international attention and became a source of inspiration for many over the course of the next century. After the fall of the Khmer Rouge regime and the end of the Civil War in the 1980s, Angkor became a focal point of the rebuilding efforts in Cambodia.

Our Involvement

An Initial Field Mission

WMF became the first Western organization to survey the temples at Angkor since the country's devastating civil war from 1975 to 1979 and its aftermath. An initial field mission in 1989 revealed the extent of damage the archaeological park had suffered after 20 years of civil strife and international isolation. The human toll of the genocide required more than just a physical intervention. When the Khmer Rouge was removed from power, no more than 100 college-educated Cambodians remained in Phnom Penh as survivors of the regime.

Three Decades of Preservation and Training

Encouraged by Cambodia's Ministry of Culture, WMF developed a set of recommendations after its initial field mission to address fundamental preservation issues at Angkor, and has since undertaken a wide variety of conservation and capacity-building initiatives at the site. In recognition of the growing threat of looting at the site, Angkor Archaeological Park was placed on the World Monuments Watch in 1996.

To restore a historical and cultural tradition to Cambodia, WMF established the Center for Khmer Studies, a permanent international research and training facility that would facilitate the exchange of knowledge between foreign scholars and their Cambodian counterparts. WMF also built a comprehensive conservation, training, and education program focusing on four key areas: the Churning of the Ocean of Milk Gallery within Angkor Wat, the gallery hosting the most prominent bas-relief; Phnom Bakheng, one of Angkor’s oldest temples; Preah Khan, an outstanding example of a large linear temple complex in a jungle setting; and Ta Som, a relatively smaller complex that is rich in architectural and sculptural detail. 

Today, WMF employs more than 70 Cambodians in our restoration work, many of whom have been with the project for more than 20 years. Angkor Archaeological Park has come to represent the Cambodia’s rebirth after a dark period and is an important contributor to the local economy.

New Support for Continued Conservation

In February 2019, the Robert W. Wilson Charitable Trust announced $2 million in funding to support preservation efforts at five WMF projects, including Angkor Archaeological Park. Funds will advance the restoration of Phnom Bakheng and the creation of a new decorative ceiling for the Churning of the Ocean of Milk Gallery at Angkor Wat.
