That Dam

That Dam is a tall brick stupa standing at a circular intersection with a darkened exterior showing signs of natural aging and weathering. The structure displays typical features of a religious monument with its distinctive shape rising prominently from the surrounding area.

The stupa dates from the 15th century and lost its gold covering during the Siamese invasion of Vientiane in 1828. This event marked a major turning point in the monument's physical appearance and condition.

Local residents see this place as sacred and connect it to a legend about a seven-headed Naga that once protected the city from invaders. This belief still shapes how people view and visit this location today.

The monument is freely accessible day and night without any entrance fees to visit. It is located near the morning market between Chantha Khoumane and Bartholonie roads, making it easy to reach from central Vientiane.

The structure has an uncommon black coloration resulting from natural aging processes that sets it apart from other religious monuments in the region. This dark patina developed over centuries of weathering and gives it a distinctive appearance.
