A uniquely designed and the most interesting temple in Nan is Wat Phumin, which has a 4-portico, single building housing both the Ubosot and Vihan. Four Buddha statues with their backs against one another are installed in the main hall facing the four directions. The doors are delicately carved in splendid designs by Lanna craftsmen.
Wat Phumin underwent a major restoration in 1867 since it was built some 27 years ago. It is believed that the wall murals were commissioned during this time. The wall paintings, in Thai Lu style are considered highly valuable and depict legends concerning the Lord Buddha as well as local legends and the local way of life, which include native attires, weaving and commerce with foreign countries.
