Bayon is the central temple within Angkor Thom (the walled city). It was erected under the reign of Jayavarman VII, towards the end of the 12th century.
The smiling face depicted on many of its towers is often called “enigmatic”. They sure make an impression. Only 37 towers are still standing among the 49 or 54.
Its exceptional bas-reliefs depict the daily life of the Khmers at the time of Angkor’s grandeur and mythological scenes. I will post those separately.
