The Old Wall in Nan is located at the junction of the Mahawong Rd and the Rob Muang Rd, at the southwest end of town. It was constructed in 1885 by Chao Anantavorarittidet, Nan’s ruler. The wall was built in place of an old log wall destroyed by a flood in 1817. Remnants of the wall, around 400 m of the original 3,600 m can still be seen. At weekends the wall is illuminated and entertainment and dining offered to visitors.
