Wat Phumin is a royal temple, located within the compound of the old city called Tambon Nai Wiang at present. It is next to the Nan National Museum. I accordance with the Nan Chronicle, Phrachao Chettabut Phormmin, a Nan ruler, constructed the temple after he had governored Nan for 6 years in 1596. It appears in the Northern Scripture that the temple was originally called “Wat Phrommin” but later became “Wat Phumin”.
