Across Ping river, there is Wat Phra Borommathat Chediyaram, situated in the centre of Mueang Nakhon Chum. Nakhon Chum was located at the mouth of Suan Mak canal on the west bank of the Ping River, opposite Kamphaeng Phet. The town was rectangular in shape, and enclosed by three earthen ramparts like those at Sukhothai. At present, the town walls and ancient monuments have almost disappeared because of road and housing construction and ground leveling for agriculture. Mueang Nakhon Chum was established during the Sukhothai period by King Li Thai. He moved the political and administrative centre from Chakangrao on the east bank to Nakhon Chum on the west bank of the Ping River. Later, King Borommaracha I of Ayutthaya combined the cities of Chakangrao and Nakhon Chum and called the whole Kamphaeng Phet. Most of the significant ancient monuments in Nakhon Chum were made of brick in the Aranyik area. Compared with the ancient monuments of Kamphaeng Phet, those of Nakhon Chum were not of vast size
