It 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.
Phnom Bakheng is one of 3 hilltop temples in the Angkor region that are attributed to Yasovarman’s reign. The other two are Phnom Krom to the south near the Tonle Sap lake, and Phnom Bok, northeast of the East Baray reservoir.
