Situated about 24 kilometers north away from Nakhon Pathom downtown, Ancient City of Kamphaeng Saen can be dated back to the Dvaravati period and is assumed be as old as Muang Nakhon Chaisi, but smaller in size. It is believed to have been constructed by Nakhon Chaisi’s former rulers to control a trading route along canals and rivers to promote the town as a seaport-trading centre.
