The Bayon is a well-known and richly decorated Khmer temple at Angkor in Cambodia. Built in the late 12th or early 13th century as the official state temple of the Mahayana Buddhist King Jayavarman VII, the Bayon stands at the centre of Jayavarman's capital, Angkor Thom. Following Jayavarman's death, it was modified and augmented by later Hindu and Theravada Buddhist kings in accordance with their own religious preferences.
The Bayon's most distinctive feature is the multitude of serene and massive stone faces on the many towers which jut out from the upper terrace and cluster around its central peak. The temple is known also for two impressive sets of bas-reliefs, which present an unusual combination of mythological, historical, and mundane scenes. The current main conservatory body, the Japanese Government Team for the Safeguarding of Angkor (the JSA) has described the temple as "the most striking expression of the baroque style" of Khmer architecture, as contrasted with the classical style of Angkor Wat.
The Bayon 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 centrepiece of Jayavarman VII's massive program of monumental construction and public works, which was also responsible for the walls and nāga-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 "devaraja" (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.
