Prasat Phanom Rung is dedicated Shiva of the Hindu pantheon Brahma-Shiva-Vishnu and is build on the top of an extinct volcano 200 metres above the Buriram plain in Southern Isan (North East Thailand).
Most of the present structure is build by a local Khmer lord, Narendraditya, in the 12th century AD, when Suryavarman II ruled in Angkor Wat.
