Thailand is a modern country firmly established in the 21st century. Despite this, there remain examples of lifestyles that have existed for centuries and continue to exist despite the advent of modernity. In and around the capital there are still a number of communities that are as they ever were - the Ban Bat community (where monk’s bowls are made) and the pottery community of Koh Kret are examples. Of course, beyond the capital traditional ways of life flourish. The hilltribes of northern Thailand are certainly communities that have resisted change, as are the seafaring communities of southern Thailand. Thailand also has a lot of communities based around occupations and trades that have profited from maintaining their traditional work approaches.
If you are in Thailand for a longer visit and you have more time to explore, the following communities might be worth a visit.
