Phnom Bakheng was constructed more than two centuries before the Angkor Wat. It is a Hindu temple originally built in the form of a temple mountain dedicated to Shiva. Historians believe that Phnom Bakheng was in its heyday, the principal temple of the Angkor region. It was the architectural centerpiece of a new capital that Yasovarman built when he moved the court from the capital Hariharalaya in the Roluos area located to the southeast.
