Once one of the major cities of the Lanna kingdom, it once served as the capital before King Mengrai established Chiang Rai in 1262. The town was captured by the Burmese in the 16th. Left a ghost town for a hundred years, it was repopulated around 1900, but still hasn’t really staggered to its feet. Traces of old double city walls and many other antiquities still remain in and outside the town. On your Upper Mekong River cruise, you can visit Chiang Saen and its National Museum, a 14th century ancient site Wat Phra That Chedi Luang, and other ancient sites.
