In the old days, Prachin Buri had a long history of civilization of about 800 years ago, since the Dvaravati period. The ruined town of “Mueang Si Mahosot” at Tambon Khokpip, Amphoe Mahosot was discovered. At Ban Khok Kwang, Amphoe Si Mahosot, east to Mueang Si Mahosot, there was an ancient community at the same period as Muang Si Mahosot .

Through the traces of the ancient towns, there were discoveries of historical venues that were used for religious purposes and historic materials such as Buddha images, earthenwares, and pottery. It was also recorded that the center of civilization has been moved to the present coast of the Bang Pakong River. There were many administration alterations, from town to Monthon, and Changwat (Province) at present.
