Legend handed down for more than 1,400 years refer to this ancient town as Hariphunchai. Its first ruler was Queen Chamthewi who was of Mon extraction. In late 12th century, King Mengrai overran the town and subsequently integrated it into the Lanna Kingdom.

Today, Lamphun still retain its enchanting ambience of a small but old community. It is some 670 kilometres from Bangkok and only 26 kilometres from Chiang Mai. Located on the bank of the Kuang River, its attractions include ancient sites and relics as well as forests and mountains and delightful lakes. Lamphun is the most famous producer of longans.
