A small Tambon (sub-district) located on the bank of the Kwai Noi River approximately 35 kilometers from the city is a site where some ancient Stone Age tools were found. In addition, a Neolithic burial site was discovered by the Dutch Allied POW, Dr. Van Hickderen who was forced to build the Death Railway. The consequences of findings revealed that Tambon Ban Kao was once a dwelling of prehistoric men. Some critical discoveries included skeletons of prehistoric men, tools made from gravel stone and axes. The Ban Kao Museum houses skeletal remains, pots, axe heads, jewelry made from animal bones, and other artifacts dating from that period.
