Phanom Rung Historical Park is an archaeological site in Thailand, covering the ruins of Prasat Phanom Rung, a Hindu Khmer Empire temple complex set on the rim of an extinct volcano at 402 metres elevation. It is located in Buriram Province in the Isan region of Thailand, and was built at a time when Khmer social-political influences were significant in Srisaket. It was built of sandstone and laterite between the 10th and 13th centuries. It was a Hindu shrine dedicated to Shiva, and symbolises Mount Kailash, his heavenly dwelling.
The Phanom Rung sanctuary compound was constructed over several phases, dated by means of iconography of its art and architectural styles together with its inscriptions. These comprise two foundations of sacred brick buildings of 10th century C.E., the minor sanctuary of 11th century, the central sanctuary built by King Suryavarman II in 12th century and two Bannalais of the 13th century.
