To hours west of banglok is a historic village that shows life in Thailand at the time of King Rama IV. The entrance is a wooden covered bridge with rows of stalls on both sides. Everywhere are costumed people doing period things, like theshing rice, and selling period products. They even have their own old currency, copper coins with holes to string them up, which must be purchased at the entrance.
On the way to Bangkok is the bridge over the river Kwai, built during the Japanese occupation 1942-45 to connect Thailand to Burma (now Myanmar). Thousands of POWs died during construction. The bridge is still in use, and also a tourist attraction. You can walk across, but must step into one of the safety platforms when a train approaches.
