In the center of Nan, a little before Wat Phumin and just opposite to the Nan National Museum, Wat Phra That Chang Kham is one of the oldest and most important temples in Nan. It dates from the early 15th century and is known locally as Wat Chang, which means the elephant temple. Its architectural style is a mixture of Lanna and Thai Lu styles.
The entrance to the viharn is guarded by two white Singha. Inside, there is a Buddha image called Phra Chao Luang and two Buddha iomages in Sukhothai style that were cast in 1426. Unfortunately, the wall paintings from the 19th century were cleared.
But above this temple houses the largest library of manuscripts in Thailand, Ho Trai, the Buddhist scripture library. Otherwise, you will also find at the back a chedi supported by elephants that gave it its local name to the temple.
