The Pha That Luang is the most important national monument in Laos, a symbol of both the Buddhist religion and Lao sovereignty. The monument looks almost like a gilded missile cluster from a distance. Surrounding it is a high-walled cloister with tiny windows, added by King Anouvong in the early 19th century as a defence against invaders.

The temple is the site of a major festival held in early November.
