Vientiane is the capital and largest city of Laos, on the banks of the Mekong River near the border with Thailand. Vientiane became the capital in 1573 due to fears of a Burmese invasion but was later looted then razed to the ground in 1827 by the Siamese (Thai). Vientiane was the administrative capital during French rule and, due to economic growth in recent times, is now the economic center of Laos. The city had a population of 820,000 as at the 2015 Census.

The name of the city is derived from Pali, the liturgical language of Theravada Buddhism. Although the original meaning of the name of the city is "city of sandalwood", as shown by ancient Lao inscriptions (written pictogrammatically, unlike modern Lao, which is written phonetically), in modern Lao the meaning of the name Vientiane is not a mystery. Vientiane is a compound word Vieng(valley) and Chan ຈັນທນ໌ sandlewood. Vientiane means valley of sandlewood. Similarly Vang Vieng means open valley.
