Old Town Hội An, the city's historic district, is recognized as an exceptionally well-preserved example of a Southeast Asian trading port dating from the 15th to the 19th century, its buildings and street plan reflecting a unique blend of influences, indigenous and foreign. Prominent in the city's old town, is its covered "Japanese Bridge," dating to the 16th-17th century.
Hội An's importance waned sharply at the end of the 18th century because of the collapse of Nguyễn rule (thanks to the Tây Sơn Rebellion – which was opposed to foreign trade).Then, with the triumph of Emperor Gia Long, he repaid the French for their aid by giving them exclusive trade rights to the nearby port town of Đà Nẵng. Đà Nẵng became the new centre of trade (and later French influence) in central Vietnam while Hội An was a forgotten backwater. Local historians also say that Hội An lost its status as a desirable trade port due to silting up of the river mouth. The result was that Hội An remained almost untouched by the changes to Vietnam over the next 200 years.
Today, the town is a tourist attraction because of its history, traditional architecture and crafts such as textiles and ceramics. Many bars, hotels, and resorts have been constructed both in Hội An and the surrounding area. The port mouth and boats are still used for both fishing and tourism.
