Prasat Preah Vihear is a Khmer temple situated atop a 525-meter cliff in the Dângrêk Mountains in Cambodia just across the border from Thailand. Affording a view for many kilometers across a plain, it has the most spectacular setting of all the temples built during the six-century-long Khmer Empire. As a key edifice of the empire's spiritual life, it was supported and modified by successive kings and so bears elements of several architectural styles. Preah Vihear is unusual among Khmer temples in being constructed along a long north-south axis, rather than having the conventional rectangular plan with orientation toward the east. The temple gives its name to Cambodia's Preah Vihear province, in which is is located, as well as the Khao Phra Wihan National Park in the Thai province Sisaket, through which the temple is mainly accessible.

The temple complex runs 800m along a north-south axis, and consists essentially of a causeway and steps rising up the hill towards the sanctuary, which sits on the clifftop at the southern end of the complex (120m above the northern end of the complex, 525m above the Cambodian plain and 625m above sea level). Although this structure is very different from the temple mountains found at Angkor, it serves the same purpose as a stylised representation of Mount Meru, the home of the gods.

The approach to the sanctuary is punctuated by five gopuras (these are conventionally numbered from the sanctuary outwards, so gopura five is the first to be reached by visitors). Each of the gopuras before the courtyards is reached by a set of steps, and so marks a change in height which increases their impact. The gopuras also block a visitor's view of the next part of the temple until he passes through the gateway, making it impossible to see the complex as a whole from any one point.

The fifth gopura, in the Koh Ker style, retains traces of the red paint with which it was once decorated, although the tiled roof has now disappeared. The fourth gopura is later, from the Khleang/Baphuon periods, and has on its southern outer pediment, "one of the masterpieces of Preah Vihear" (Freeman, p. 162): a depiction of the Churning of the Sea of Milk. The third is the largest, and is also flanked by two halls. The sanctuary is reached via two successive courtyards, in the outer of which are two libraries.


Ancient History

Construction of the first temple on the site began in the early 9th century; both then and in the following centuries it was dedicated to the Hindu god Shiva in his manifestations as the mountain gods Sikharesvara and Bhadresvara. The earliest surviving parts of the temple, however, date from the Koh Ker period in the early 10th century, when the empire's capital was at the city of that name. Today, elements of the Banteay Srei style of the late 10th century can be seen, but most of the temple was constructed during the reigns of the kings Suryavarman I (1002–1050) and Suryavarman II (1113–1150). An inscription found at the temple provides a detailed account of Suryavarman II studying sacred rituals, celebrating religious festivals and making gifts, including white parasols, golden bowls and elephants, to his spiritual advisor, the aged Brahman Divakarapandita. The Brahman himself took an interest in the temple, according to the inscription, gifting it with a golden statue of a dancing Shiva.
