Hoi An Ancient Town is an exceptionally well-preserved example of a South-East Asian trading port dating from the 15th to the 19th century. Its buildings and its street plan reflect the influences, both indigenous and foreign, that have combined to produce this unique heritage site.

The Mỹ Sơn temple complex is regarded one of the foremost Hindu temple complexes in Southeast Asia and is the foremost heritage site of this nature in Vietnam. It is often compared with other historical temple complexes in Southeast Asia, such as Borobodur of Java in Indonesia, Angkor Wat of Cambodia, Bagan of Myanmar and Ayutthaya of Thailand. As of 1999, My Son has been recognized by UNESCO as a world heritage site. At its 23rd meeting, UNESCO accorded Mỹ Sơn this recognition pursuant to its criterion C (II), as an example of evolution and change in culture, and pursuant to its criterion C (III), as evidence of an Asian civilisation which is now extinct.
