ピン川
Kamphaeng Phet was an ancient outpost town during the Sukhothai period, as evidenced by the city walls and fortifications that remain today. Before the creation of the city, legends says that there were two cities present in the location; Chakangrao (ชากังราว) and Nakhon Chum (นครชุม). Chakangrao was built on the east bank of the Ping River while Nakhon Chum was built on the west bank of the Ping River.
