Kamphaeng Phet Province, a historic city in lower northern Thailand, has served as an important defensive and economic center since the Dvaravati period. Known in the past as “Cha Kang Rao,” Kamphaeng Phet was strategically positioned as a frontier city of the Sukhothai Kingdom, surrounded by vassal towns like Tri Truang and Thep Nakhon. It played a vital role in defending against invasions and protecting key trade routes. The city gained further significance under King Taksin, who governed here as "Phraya Wachiraprakan" before rising to the throne.

Kamphaeng Phet is renowned for its ancient city walls, moats, and temples, which highlight its military and cultural significance. The province features two ancient urban centers: Cha Kang Rao, founded on the eastern banks of the Ping River by King Lo Thai around 1347, and Nakhon Chum on the western side, built under King Li Thai. These historic sites are now part of the Kamphaeng Phet Historical Park, designated a UNESCO World Heritage Site in 1991.

Today, Kamphaeng Phet remains an important cultural and archaeological destination, attracting visitors to its unique laterite structures and ancient ruins. The province is also known for its rich natural resources, with the Ping River providing fertile land for agriculture, and its mountainous western region housing minerals and headwater streams. Kamphaeng Phet’s emblem features a gem-studded wall, symbolizing the city’s historic strength and unity, while the province’s flag colors—yellow, red, and green—reflect its ancient heritage, warrior history, and abundant natural resources.
