aspect. Over 200 large faces carved in the 54 towers give this temple its majestic character, which at that time represents the 54 provinces in debated by scholars and some think they represent the Bodhisattva Avalokiteshvara, in keeping with the Buddhist character of the temple, it is generally accepted that the four faces on each o the towers are images of King Jayavarman VII and signify the omnipresence of the King.
