Chiang Mai's Old City Wall

The old city of Chiang Mai, once the capital of the Lan Na in Northern Thailand, was fortified with a nearly square wall and moat to fend against the threat of neighboring dynasties in the 13th century. Since then Chiang Mai has grown far beyond its walls  to become the second-most important city in Thailand after Bangkok in the south. Numerous restorations of the old city walls have taken place and are continuing today on the corners and around the five original gates. This portion on the Southeast corner of the wall, where today Moonmurang and Bumrungburi roads meet, is one of the four corner bastions, known as Jaeng Katam.
