The Old City Wall of Songkhla is located on Chana Road in the Bo Yang sub-district. Construction began in 1856 during the reign of King Rama III, following an order from Bangkok to build walls and forts. However, construction was not completed in time before the Malay city-states rebelled in 1838, attacking and burning Chana. Phaya Wichienkhiri (Thian Seng) defended Songkhla until reinforcements arrived from Bangkok, successfully repelling the Malay forces. The city walls were finally completed in 1842. The walls were constructed using square stones and mortar, surrounding Songkhla with a length of 1,200 meters from north to south. The walls stand 5 meters high and are 2 meters thick, featuring eight bastions with four-inch cannons, three to four per bastion. The main entrance consists of a large archway with ten doors, surrounded by ten smaller doors. Today, only sections of the wall remain along Chana Road, opposite the National Museum, and on Nakorn Nai Road.
