Phnom Bakheng (Khmer: ប្រាសាទភ្នំបាខែង) at Angkor, Cambodia, is a Hindu and Buddhist temple in the form of a temple mountain.:103 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.
Constructed more than two centuries before Angkor Wat, Phnom Bakheng was in its day the principal temple of the Angkor region, historians believe. It was the architectural centerpiece of a new capital, Yasodharapura, that Yasovarman built when he moved the court from the capital Hariharalaya in the Roluos area located to the southeast.:112-113
An inscription dated 1052 AD and found at the Sdok Kak Thom temple in present-day Thailand states in Sanskrit: "When Sri Yasovardhana became king under the name of Yasovarman, the able Vamasiva continued as his guru. By the king's order, he set up a linga on Sri Yasodharagiri, a mountain equal in beauty to the king of mountains." Scholars believe that this passage refers to the consecration of the Phnom Bakheng temple approximately a century and a half earlier.:112
Surrounding the mount and temple, labor teams built an outer moat. Avenues radiated out in the four cardinal directions from the mount. A causeway ran in a northwest-southeast orientation from the old capital area to the east section of the new capital's outer moat and then, turning to an east-west orientation, connected directly to the east entrance of the temple.
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.:355,358-360 At the top level, five sandstone sanctuaries, in various states of repair, stand in a quincunx pattern—one in the center and one at each corner of the level’s square. Originally, 108 small towers were arrayed around the temple at ground level and on various of its tiers; most of them have collapsed.
Jean Filliozat of the Ecole Francaise, a leading western authority on Indian cosmology and astronomy, interpreted the symbolism of the temple. The temple sits on a rectangular base and rises in five levels and is crowned by five main towers. One hundred four smaller towers are distributed over the lower four levels, placed so symmetrically that only 33 can be seen from the center of any side. Thirty-three is the number of gods who dwelt on Mount Meru. Phnom Bakheng's total number of towers is also significant. The center one represents the axis of the world and the 108 smaller ones represent the four lunar phases, each with 27 days. The seven levels of the monument represent the seven heavens and each terrace contains 12 towers which represent the 12-year cycle of Jupiter. According to University of Chicago scholar Paul Wheatley, it is "an astronomical calendar in stone." 
Phnom Bakheng is one of three 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.:113
Following Angkor's rediscovery by the outside world in the mid-19th century, decades passed before archeologists grasped Phnom Bakheng's historical significance. For many years, scholars' consensus view was that the Bayon, the temple located at the center of Angkor Thom city, was the edifice to which the Sdok Kak Thom inscription referred. Later work identified the Bayon as a Buddhist site, built almost three centuries later than originally thought, in the late 12th century, and Phnom Bakheng as King Yasovarman's state temple.:112
Later in its history, Phnom Bakheng was converted into a Buddhist temple. A monumental Sitting Buddha, now lost, was created on its upper tier. Across its west side, a Reclining Buddha of similar scale was crafted in stone. The outlines of this figure are still visible.
