If you visit Nan there is one must-see attraction above all others; Wat Phumin. This royal temple was built by the ruler of Nan, Prachao Chetabut Phrommin, in 1596. Originally named after him and written in the local language as Wat Phrommin, somewhere in history the name became ‘Phumin’. From the outside, the temple may appear similar to many others seen in Thailand, but a closer look reveals the temple has been subtly designed to look like it is being supported by two giant guardian serpents or nagas. But it is only once inside the wat that the full beauty of the temple is revealed.
