If you are planning to visit Autthaya, you should hop on the train after and make one more stop in this small city near by. Lopburi is an ancient capital and actually one of the oldest towns in Thailand. It’s history going back more than 1000 years back. However nowadays it’s mostly known for a bit different reason than in the history. Lopburi is popular among the travelers because of the cheeky little monkeys sharing the city with humans.
