Hoi An, 30km south of Danang, was one of South-East Asia's main sailing ports from the 17th to the 19th century. It was a good material manifestation of the fusion of cultures over time in an international commercial port, and is still exceptionally well preserved. The city has retained a unique character, as there are still a thousand of very concentrated historical structures, and no modern development. It is a quiet and friendly place where you can still be transported one hundred years ago to a colorful past. The Hoi An Ancient Town is a UNESCO World Heritage Site.
