Formerly situated by the sea, the city prospered during the Dvaravati civilisation. According to archaeological findings, Nakhon Pathom was the first city to possess influences of Buddhism and Indian civilisations. From the Phra Pathom Chedi and other remains discovered in the city area, it is believed that the city was a centre of civilisation in that era. People of different races settled in Nakhon Pathom. However, a change in the course of the river caused a draught that forced the people to migrate and settle on the banks of river, and these communities developed into towns.
