Phanom Rung is one of Thailand's most amazing Khmer architecture site, aged over a thousand years old. Built on an extinct volcano, it was originally a Hindu religious site and later became a Buddhist one. Several additions were made during the 15th-18th Buddhist century.
The large main pagoda has a square base facing the East. Exquisite designs on the pagoda, columns, doorway, and lintels tell a story of Hindu gods. Each building features descriptive motifs reciting a purpose of its construction, functionality and beliefs of ancient people.
Based on these intricate designs and architecture, it is surmised that the pagoda, the stairway and the Naga Bridge were all built during the 17th Buddhist century.
