Prasat Phanom Wan is in Ban Makha, Tambon Pho, around 15 kilometres from the city on the Nakhon Ratchasima-Khon Kaen road. A sign on the right shows the way on a road 5 kilometres more. This is an interesting Khmer sanctuary. It is believed that it was built in the 15th Buddhist century. Later during the 18th-19th centuries, a stone building was built over it. From inscriptions found at the site, it is known that the sanctuary was used in the Hindu religion and later became a Buddhist site. Although most of it is in ruins, there is a clear form present, like the square main pagoda facing east and a tiered pagoda in front, as well as a path linking the two structures.
To the southwest is a building of red sandstone called “Prang Noi.” Inside is a large stone Buddha image. A roofed sandstone walkway and a laterite wall go around the sanctuary. A Gopura (a sanctuary doorway or porch) in the form of a tall tower is situated in all 4 directions. Around 230 metres east of the sanctuary are traces of a moat and an earth hill that was the site of another Khmer building called “Noen Oraphim.”
