Wat Xieng Thong is a Buddhist temple (wat), located on the northern tip of the peninsula of Luang Phrabang, Laos.It was built in 1560 by King Setthathirath and was under royal patronage during the Kingdom of Laos. Like the royal palace, the wat was placed near the mekong. In 1880, the Tripitaka library was added and then the drum tower in 1961. This temple, along with Wat Suwannaphumaham, was spared by any damage during the sacking of the city in 1887. This was because the Black Flag Haw leader, Deo Van Tri, had studied here as a monk in his early life, and used it as his headquarters during the sacking of Luang Phrabang.
