Nan is a northern border of Thailand, about 668 kilometers from Bangkok, covering an area of 11,472 square kilometers or approximately 7 millions rai. It is embraced by mountains and recognized as a land of east Lanna in Sukhothai. The assumption is that approximately during the 12th century B.E., Praya Phuka built a city on the plain land in the upper part of Tambon Silapetch or so nowadays called Amper Bua. The former name of Nan is Nundhaburi or Woranakorn. Until the time of Praya Karn Muaeng, he had received 7 Buddhas relics from Sukhothai and brought the relics to be kept in Doi Phu Piang Chae Haeng. In the year 1911 B.E., the tide of Nan River changed its direction causing draught, so the city had to be moved to Ban Huay Tai in the west bank of Nan River.
