Phnom Bakheng at Angkor, Cambodia, is a Hindu and Buddhist temple in the form of a temple mountain. Dedicated to Shiva, it was built at the end of the 9th century, during the reign of King Yasovarman (889-910). Located atop a hill, it is nowadays a popular tourist spot for sunset views of the much bigger temple Angkor Wat, which lies amid the jungle about 1.5 km to the southeast. The large number of visitors makes Phnom Bakheng one of the most threatened monuments of Angkor. Since 2004, World Monuments Fund has been working to conserve the temple in partnership with APSARA.
Phnom Bakheng is a symbolic representation of Mount Meru, home of the Hindu gods, a status emphasized by the temple’s location atop a steep hill 65 m above the surrounding plain. The temple is built in a pyramid form of seven levels, representing the seven heavens. Originally, 108 small towers were arrayed around the temple at ground level and on various of its tiers; most of them have collapsed. (
