Wat Phra That Sadet is located some 15 km northeast of the city. Onsite information states that legend has it that this temple was built 500 years ago* in the reign of Phranang Chammathewi. The Phra Ubosot and Viharn have been restored, the original artistic features having been maintained. The temple was declared an ancient monument by the Fine Arts Department.

Note*: The discrepancy in the timeline as probably due to the fact that some religious building did exist during Queen Chamathewi’s reign (7th Century) but during the Lanna era, art and culture of the Hariphunchai kingdom were retained and temples resorted as a reminder of the origin and independence of the region.
