Phimai Historical Park is situated in Phimai, 60 kilometers northeast of Nakhon Ratchasima.
Prasat Hin Phimai is a Mahayana Buddhist sanctuary and the largest Khmer temple compound in Thailand. It was likely built during the reign of Suryavarman I (King from 1010 till 1050) of the Khmer empire. Suryavarman I was a Buddhist ruler.
The sanctuary at Phimai has three main temple structures : the main tower, the Brahmadat tower and the Redstone tower. As other Khmer sanctuaries, Prasat Hin Phimai symbolizes Meru Mountain, the center of the universe, and abode of the Gods.
