This Hindu sanctuary, evidence of an old civilization, is located in Nang Rong district, on the top of Khao Phanom Rung, an inactive volcano. It was left unattended and in ruins for many centuries until 1935, when the Fine Arts Department registered it and declared it a national protected archeological site.
A major renovation using modern techniques began in 1971 and was completed in 1988. The restoration effort took 17 years to restore the sanctuary to a state as close as possible to its original.
