The Bayon was built by Khmer king in 12th century in the heart of Angkor Thom city and the only Angkorian state temple to be built primarily to worship Buddhist deities, though a great number of minor and local deities were also encompassed as representatives of the various districts and cities of the realm. Originally a Buddhist temple, the Bayon (Jayagiri) was the centerpiece 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. It is the most attraction of tourists all over the world and can also see the giant faces of Buddha.
