Nakhonayok Province 
            Nakhonayok province had been in Thawaravadhi era. There are hillock and bar of canal at Dong La-Korn sub-district. The city name was appeared in Krungsri-Ayutthaya as frontier city on east side in the reign of Phra Chao Authong. The former name is "Muang Ban-Na" or Ban-Na city where was thick forest and upland. People here could not do agriculture successful so that they immigrated to other cities. The king knew the problem and waived tax for farmland in order to persuade local people to come back again. This plan was success and people came back until becaming a large community. It was called "Muang Na-Yok" and slightly distorted to "Nakhon Na-Yok" from time to time because meaning of word "Nakhon" is bigger than "Muang". In year 1894, Rama V reformed administration system to be precinct governed so that Nakhonayok was aggregated to Prachinburi city. Until year 1902, the old administration system was cancelled and reformed to provincial governed system. Nakhonayok was established to be Nakhonayok province until now.
