It was assumed that Wat Fa Wiang In was built in the reign of King Naresuan the Great. Later on the General Pomoheng—the leader of TRC: Tai Revolution Council immigrated to Piang Luang Village in B.E.2509 and his armies had the great opportunity from His Majesty King Bhumibol Adulyadej to settle down this area. They then found this stupa deteriorated and very old. After that, they all restored the stupa bit by bit until completely. This temple has become prosperous since B.E. 2511, and Shan United Revolution Army: SURA was settled down here.
