Each of the four entrances is preceded by a small corridor topped by a finely decorated, point-shaped structure (underlining the royal origin of the temple) and is equipped with smoothly carved doors; with Chinese demon guards in the east, flowers in the north and forest life motives in the Lanna style in the west and south.
The structure of the roof is supported by twelve teak pillars decorated with gold on black and red lacquer and elephants' motives.
Well preserved murals of great value illustrating the Khattana Kumara Jataka on the Northern wall and the Nimi Jatakas on the Western wall as well as scenes of the local life of the time when they were painted by Thai Lue artists during the restoration of the temple at the end of the 19th century.
The setting of the murals at Wat Phumin however, is that of the culture and everyday life of the Thai Lue people.
The large paintings on each side of the main entrance show a Chinese influence which can be explained by the origins of the Thai Lue people.
