Prasat Ban Prang was built in the 11th century in Bapuon style but may have been completed early in the 12th century with Angkor Wat style influence. The sanctuary was built of sandstone and laterite. Presently just one sanctuary exists but it is believed there were two additional towers on the same single base aligned north – south. The monument is surrounded by a U-shaped moat, except at the eastern entrance. This sanctuary also contains another building of newer construction. This building seems to be an early example of a viharn or Hor phra, an assembly building for the followers of Theravada Buddhism that would become the dominant religion. This would have housed a Buddha image. The sanctuary was built from brick with the roof tiles probably made of wood. The Ban Prang Nakhon sanctuary was first registered as a national ancient monument in December 1954 and was visited by the King in 1983.
