Mahasiti Temple is located on the west side of the Reclining Buddha Temple in Ruidariang. It was built in 1560 by the Emperor Mang Yinglong of the Tunku Dynasty. Because in the Buddhist tradition, only the kings who can help the development and spread of Buddhism have the legitimacy of rule, it is said that in order to consolidate his rule, Mang Yinglong personally welcomed the Buddha tooth relic from Sri Lanka and placed it in the Mahasiti Temple. After several tossings, the tooth was finally placed in the Gongmudu stupa in Sagaing. It is a pity that later this sacred "Buddha Tooth" was proved to be nothing but a fake. Mahasiti Temple also experienced a lot of wars and sufferings, and due to earthquakes and other reasons, the renovation was not successfully completed until 1982. Regardless of the tortuous history of the Buddha tooth, the architectural style of Mahasiti Temple is also unique in southern Myanmar. The top of the stairs leading to the golden pagoda are decorated with small pagodas, and the temples are decorated with uniform wavy golden apexes from multiple angles. From a distance, they reflect each other with the white walls and are very beautiful.
