The Wat Phumin is famous for its beautiful and colorful 19th century mural paintings, that cover much of its interior walls. While some of the murals have largely vanished, some of them are in an excellent condition. The murals show scenes of daily life in the 19th century as well as depictions of the previous lives of the Buddha.
Depictions of 19th century daily life show a city and its docks, sailing ships and a steamship, a horse drawn chariot, people smoking and playing musical instruments, Europeans in a boat and several animals like birds and elephants. The most famous depiction is that of a couple, the man with tattoos on arms and chest whispering in the woman’s ear.
