Bayon Temple is a Buddhist symbolism in the foundation of the temple by King Jayavarman VII According to scholars, it is no coincidence that this portrait of King Jayavarman VII, located today in the Musée Guimet in Paris, bears a strong resemblance to the face towers of the Bayon.

The Bayon Temple was the last state temple to be built at Angkor, and the only Angkorian state temple to be built primarily as a Mahayana Buddhist shrine dedicated to the Buddha, though a great number of minor and local deities were also encompassed as representatives of the various districts and cities of the realm. It was the centerpiece of Jayavarman VII’s massive program of monumental construction
and public works, which was also responsible for the walls and naga-bridges of Angkor Thom and the temples of Preah Khan, Ta Prohm, and Banteay Kdei.

The similarity of the 216 gigantic faces on the temple’s towers to other statues of the king has led many scholars to the conclusion that the faces are representations of Jayavarman VII himself. Others have said that the faces belong to the bodhisattva of compassion called Avalokitesvara or Lokesvara.The two hypotheses need not be regarded as mutually exclusive. Angkor scholar George Coedès has theorized that Jayavarman stood squarely in the tradition of the Khmer monarchs in thinking of himself as a “deva-raja” (god-king), the salient difference being that while his predecessors were Hindus and regarded themselves as consubstantial with Shiva and his symbol the lingam, Jayavarman as a Buddhist-identified himself with the Buddha and the bodhisattva.

Bayon Temple Alterations following the death of Jayavarman VII

Since the time of Jayavarman VII, the Bayon has suffered numerous additions and alterations at the hands of subsequent monarchs. During the reign of Jayavarman VIII in the mid-13th century, the Khmer empire reverted to Hinduism and its state temple was altered accordingly. In later centuries, Theravada Buddhism became the dominant religion, leading to still further changes, before the temple was eventually abandoned to the jungle. Current features which were not part of the original plan include the terrace to the east of the temple, the libraries, the square corners of the inner gallery, and parts of the upper terrace.
