Pha That Luang (great stupa) is the most important national monument in Laos
Pha That Luang (Paa T-had Lu-uang) (Great Stupa in Lao) is a Buddhist stupa in Vientiane, Laos. It was built in the 16th century under King Setthathirat on the ruins of an earlier 13th century Khmer temple, which the Lao believe was in turn built on a 3rd century Indian temple built by Buddhist missionaries from the Mauryan Empire who were sent by the Emperor Ashoka.[citation needed] Relics of The Buddha are said to be contained here.
