The Bayon temple forms a square at the center of the much larger square of the vast Angkor Thom, and is the architectural highlight of the complex. This was considered by the Khmers to be the conjunction of heaven and earth, though the auspicious site was covered in jungle for centuries.

Like much in the area it dates to the 12th-century reign of King Jayavarman VII, and is particularly noted for its magnificent carved stone faces with their beatific smiles. They depict either the king himself or a bodhisattva; the confusion was probably deliberate.

The bas relief carvings on the temple’s outer walls are a riot of scenes depicting everything from celestial beings and mighty battles to humble village life.
