Description : In northern Laos, enclosed in the mountains, the peaceful city of Luang Prabang has prospered for centuries within the peninsula formed by the confluence of the Mekong River and the Nam Khan River. Before being overtaken by Vientiane, it was the capital of the powerful Kingdom of Lane Xang (Kingdom of the Million Elephants). Its colonial architecture and majestic temples have earned it a UNESCO World Heritage Site since 1995. Laos.
