Muang Nong Han Luang
Muang Nong Han Luang stood beside the great freshwater lake of Nong Han, in the basin north of the Phu Phan hills. Local tradition traces the town, later called Sakon Nakhon, to the time of Khmer rule. At Phra That Choeng Chum, a Khmer inscription from around the twelfth century records the allocation of land. The shrine later became an important Buddhist centre and was known as Phra That Nong Han in the Lan Xang era.
