I’ve published photos of dilapidated traditional Jeju houses before but they’re being preserved in the Jeju folk village. It’s well worth a visit; it’s an interesting mixture of museum and living village and it’s not always obvious which are private houses and which are open to the public. Having said that, some of the buildings have rows of benches for visitors and local products for sale, both indications that the village caters for tour buses. And although I’ve posted photos which avoid 21st century details, there are plenty of modern houses and telegraph wires, and the buses need somewhere to park, of course.
