Modern day Laos was once known as the Kingdom of Lan Xang, the Kingdom of a Million Elephants. Its founding goes back to King Fa Ngum in 1353 but it reached the zenith of its power in the sixteenth century. During a period of about fifty years three kings extended the power of Lan Xang to reach over all of modern day Laos and Northern Thailand. During this time these kings promoted Buddhist culture and built some of the most important Buddhist temples and stupas in Laos, sites which today are still highly revered by the Lao people whilst being promoted as major tourist attractions. In this article we visit five of these magnificent Buddhist sites and explain their place in Lao history.
