Chakangrao
Chakangrao stood on the eastern bank of the Ping River, opposite Nakhon Chum. The city later known as Kamphaeng Phet was protected by walls of local laterite, with Buddhist monuments both inside and beyond the fortified enclosure. Its position on the river made it an important frontier centre between the northern kingdom of Sukhothai and Ayutthaya to the south. The two neighbouring towns developed on opposite sides of the Ping, sharing artistic traditions while guarding a contested route.
