Bo Yang
In 1836, King Rama III instructed Phraya Vichiankiri (Tianseng) to build the city wall fortress. During the construction of the wall, Tuanku Ahmadsa-adtogether with the rulers from Syburi, Pattani and 7 other provinces, attacked Songkhla. After their conquering all the rebellion, the fortress and the city wall were carried on. Also, the city pillar was set up and the town of Songkhla was moved to the east of Laem Son called Bo Yang District, which is now in the area of Songkhla Municipality.
