Lamphun Old City Wall

Lamphun Old City Wall is the preserved fortification encircling the historic centre of Lamphun town in Nai Mueang, Mueang Lamphun District, Lamphun Province, northern Thailand. Built to protect the ancient Mon city of Hariphunchai, the earthen rampart and brick wall with moat and gates define the old city's rectangular layout. Today, restored sections, gates and the surrounding moat remain visible, offering insight into early northern Thai urban planning and defensive architecture.

Visitors can expect to see restored sections of the earthen and brick city wall and moat that outline the rectangular old city in central Lamphun. The wall is interspersed with historic gates, notably Pratu Li, and tree-lined moat areas. The setting is an urban historic area with quiet streets, temples and local houses inside the walls. Visitors can walk or cycle along the moat and wall perimeter, view information signs, and photograph the gates and ramparts.

The wall is part of the fortifications of Hariphunchai, a Mon Dvaravati city traditionally founded in the 7th-8th century by Queen Chamadevi. The earthen rampart, brick wall and moat protected the political and religious centre of the Hariphunchai Kingdom until its incorporation into the Lanna Kingdom in the late 13th century. The surviving layout illustrates early northern Thai defensive architecture and urban planning.

The wall defines the historic and cultural core of Lamphun, one of Thailand's oldest continuously inhabited cities. It remains a landmark of local identity and is associated with the Hariphunchai heritage, Buddhist temples and traditional community within the old city. The gates and moat are used as reference points for cultural events and heritage interpretation.
