The wall paintings at Wat Phumin depict scenes from the Buddhist Jataka stories which represent the past lives of Buddha. More importantly perhaps, the murals are a historical record of life in Nan showing scenes of everyday life and the traditions of the Thai Lue people who had settled in the area. The distinctive murals are the work of Thai Lue artist, Thit Buaphan and took him more than 20 years to complete. The most famous mural scene was labelled by the artist in the local dialect as ‘Poo Marn Yar Marn‘ (‘Whispering of Love’) but has become better known to most Thais as ‘Grasip‘ which translates to English as the ‘Whispering’.
