I was lucky enough to be invited to visit Yangdong village by a colleague. Yandong village is listed as a Korean Cultural Heritage site and is being reviewed by UNESCO now. It was first developed in the 15th century and most of the homes in the village were origanally built in the 16th century. They have had some modern amenities added, but for the most part they look the same as they did 400 years ago.
People still live in most of the homes so you still see people working in their little gardens and the homes looked lived in because they are. My colleague, who is an incredibly sweet woman, used to visit her grandmother who lived in Yangdong every summer. Quite cool.
