A Closer Look

Phnom Bakheng

Home of the gods

Phnom Bakheng, the state temple of the first Khmer capital in the Angkor region, survives as one of the world’s greatest architectural treasures. The Temple of Phnom Bakheng was constructed between the late ninth and the early tenth century by Yasovarman I as the centerpiece of his new capital, known as Yasodharapura. It was abandoned only a few decades after its construction, but its privileged hilltop location makes it unique among the temples of Angkor. Its stepped pyramid construction is a built representation of Mount Meru, home of the Hindu gods. Shrines and guardian lions adorn the five levels of terraces that make up the pyramid; decreasing in size towards the top of the temple, these enhance the impression of the temple’s height. Five shrines on the top platform, arranged in a quincunx formation, represent the five peaks of Mount Meru. In the sixteenth century, an attempt was made to construct a large seated Buddha around the central shrine, which has since been dismantled. The central temple was surrounded by multiple brick towers, which only survive as ruins. Today, Phnom Bakheng is a popular spot for panoramic views of the Angkorean landscape, often enjoyed by visitors at sunset.

A visionary plan

In 2004, World Monuments Fund began to survey, analyze, and plan for the conservation of the site, thanks to a grant of $550,000 from the U.S. Department of State. The result of this effort, built on the contributions of international and local experts, was the 2007 Phnom Bakheng Conservation Master Plan. Since then, WMF and the APSARA National Authority have collaborated to advance the vision of this comprehensive plan through emergency repairs, carefully executed conservation interventions, and improved visitor management. Support from the U.S. Department of State was generously renewed in 2008, 2011, 2013, and 2015, helping to expand the scope of the project. Additional funds have been provided by the Ralph E. Ogden Foundation and the Robert W. Wilson Challenge to Conserve Our Heritage. Throughout the project, the APSARA National Authority has contributed additional personnel and materials. The total financial commitment to this project has been more than $5 million.

An ambitious project is underway

With a major grant from the U.S. Department of State, WMF launched the second phase of the project in 2008: stabilizing and restoring the east half of the central temple and improving water management at the site to ensure the temple’s preservation well into the future. As part of the ongoing program, conservation begins with documentation of current conditions, and proceeds with disassembly of walls, terraces, and other unstable structures to allow for the structural repair of the terrace foundations. To repair the foundations underneath the terraces, the bedrock is pinned using rock bolts, and new stones are inserted in areas of loss when necessary. The waterproofing plan involves covering the foundation with a PVC membrane and, in some cases, an added layer of lead sheets. All original stones are cleaned and conserved, while missing wall sections are reconstructed using stone blocks retrieved from the side of the hill of Phnom Bakheng, as well as new stones from the original quarry.

Sustainable visitor management

Though the rapid rise in tourism has brought welcome economic growth to Cambodia, the impact of visitors has imperiled Phnom Bakheng’s stability. In 2011, World Monuments Fund and the APSARA National Authority jointly elaborated a set of policies designed to alleviate overcrowding at Phnom Bakheng and to mitigate the effects of visitors on the physical condition of the monument. This plan, which limits the number of visitors at the top platform during sunset, is a milestone in the ongoing effort to improve the management of Angkor as a tourism destination.

The people behind the project

Since the early 1990s, World Monuments Fund’s activities at Angkor have allowed dozens of Cambodian employees to learn alongside international specialists, who have helped WMF develop and implement appropriate conservation programs. The Phnom Bakheng project is carried out by World Monuments Fund’s skilled Cambodian staff, with oversight from Cambodian professionals and in collaboration with foreign experts. It enables the employment of more than 100 full-time workers, most of whom live in the villages within the archaeological park, highlighting the deep and lasting connection between the community and its heritage. WMF’s local workforce includes individuals who have been employed since the early 1990s and have continued to mentor younger workers over the years.
