That Dam



That Dam (Lao ທາດດຳ, meaning Black Stupa) is a large stupa located in Vientiane, Laos. The stupa is situated in the middle of the roundabout between Chantha Khoumane road and Bartholonie road.

Many Lao people believe it is inhabited by a seven-headed nāga who tried to protect them from an invasion by the Siamese army in 1827.
