Construction on Wat Phra Singh began in 1345 when King Phayu, the fifth king of the Mangrai dynasty, had a chedi built to house the ashes of his father King Kham Fu. A wihan and several other buildings were added a few years later and the resulting complex was named Wat Lichiang Phra. When, in 1367, the statue of Phra Buddha Singh was brought to the temple, the temple complex received its present name. During restoration works in 1925, three funerary urns were discovered inside a small chedi. It was assumed that these contained royal ashes. The urns have since been lost.
