Rulers’ New and Old Palaces are located near Wat Wang. Once they served as a residence cum office of the governors of Phatthalung. Nowadays, some parts of them remain. Wang Kao or the old palace was built during the rule of Phraya Phatthalung (Noi Chantharotwong). Later, the palace was inherited to Praphai Mutamara, a daughter of Luang Si Worachat. Wang Mai or the new palace was built in 1889 by Phraya Aphaiborirak Chakkrawichit Phiphitphakdi (Net Chantharotwong), a son of Phraya Phatthalung who was the ruler of the city of Phatthalung at that time. The heirs of the Chantharotwong family gave the old and new palaces as national treasures to the Fine Arts Department. The palaces were registered as an ancient monument in 1983.
