Wat Visoun, otherwise known as Wat Wisunarat, is located at the corner of Monomai and Phomathat Roads in the same compound as Wat Aham in Luang Prabang, Laos. Wat Visoun was built in 1513 and is one of the oldest buildings in Luang Prabang and considered the oldest operating Wat in the region.
The Phra Bang Buddha statue once took residence in this Wat from 1867 to 1894 before it was transferred to Wat Mai. It currently houses the largest Buddha image in Luang Prabang, the Phra Chao Ong Luang.
Outside the Wat you can find the That Makmo, also known as the Melon Stupa. It once contained hundreds of buddha images which currently are stored in Royal Palace Museum for safekeeping.
