Originally built in 1513 during the reign of Chao Wisunarat (King Visoun), Wat Wisunarat is the oldest operating temple in Luang Prabang. It was rebuilt between 1896 and 1898 following an 1887 fire set by Black Flag Haw raiders. The original was wooden, and in the brick and stucco restoration the builders tried to make the balustraded windows of the sǐm appear to be fashioned of lathed wood (an old South Indian and Khmer contrivance that is uncommon in Lao architecture).
