Major features in the Kamphaeng Phet Historical Park include archaeological remains of ancient sites such as Mueang Chakangrao to the east of the Ping River, Mueang Nakhon Chum to the west and Mueang Trai Trueng some 18 km from the town to the southwest. Chakangrao, the ancient Kamphaeng Phet town, had the same town planning concept as the old Sukhothai and Si Satchanalai, with separate zones for religious sites both within and outside of town limits. Structures are usually large and made of laterite. Religious sites on the west bank of the Ping River at Nakhon Chum are built of bricks and of smaller size.
City walls and old fortifications mark the boundary of the rectangular town area, measuring 300-700 metres wide and 2,200 metres long.
