That Xieng Tung (Xieng Teung Stupa) is the most important stupa in Muang Sing, because it is said to contain the Adam’s apple of Buddha. The construction date is unknown. To the left of the stupa are some steps which lead to a sacred fountain and a sacred stone. If you follow a path to the right of the stupa (be careful!) downhill, you might be able to find the old moat and wall of the stupa.
The biggest festival of the year, That Xieng Teung Festival, is held here during the full moon of the 12th lunar month (usually in late October or early November) and attracts a wide gathering from villages and people around the district and Luang Namtha province.
The stupa is located 5.5 km from the center of town, on the road towards Luang Namtha, situated on the top of a hill. There is a large dirt road leading up to it on your right if you are coming from Muang Sing.
