The name “Chumphon” first appeared in the year 555 in Nakhon Si Thammarat’s myths about Buddha’s relics (National Library’s version). It stated that Chumphon was one of “twelve subordinate cities” of Nakhon Si Thammarat. The city’s seal was the picture of a goat. It was a northern frontier city of Nakhon Si Thammarat, as it was located on the upper part of the southern region, and therefore in between the route from Ayutthaya to the south. In the year 1454, under the reign of Somdet Phra Ramesuan Boromma Trailokkanat Bophit, the Three Emblems Law stated that Chumphon was a Tri level city and a southern frontier of Ayutthaya. In the year 1916, it became a province of Monthon Surat Thani
