Kamphaeng Phet province is located south of Sukhothai province, and is 358 km away from Bangkok. Kamphaeng Phet was formerly also known as Nakhon Chom. Settlements along the Ping River were present in the 11th century. The region for a while was an outpost of the Khmer Empire, and later in the 13th century became part of the Sukhothai Kingdom. Kamphaeng Phet was not mentioned on the early Sukhothai inscription stones (while other cities were), indicating that it was initially not incorporated into the Kingdom or not of great importance. However it was recognized as a town of significance during the reign of King Li Thai.
The Kamphaeng Phet historical park has been established at the Old City site, and the area is now being cared for by the Fine Arts Department.
While not quite on the scale of Sukhothai or even Si Satchanalai, the Kamphaeng Phet historical park covers an extensive area, located mostly within surrounding forests. The Royal Palace itself has been destroyed. Wat Phrakaew is the largest monastery and located adjacent to the old Royal Palace. It contains several wihans (viharas), an ordination hall, and a large chedi. There are some restored Buddha images on the site.
Scattered throughout the forest are the Aranyik Ruins. These remain of the many forest monasteries that were prevalent at the time of the old city. Most date to the 14-16th centuries.
