The most highly revered stupa in Loei Province, this whitewashed Lao-style chedi stands 20m high and was built in 1560–63 on what was then the Thai–Lao border as a gesture of unity between the Lao kingdom of Wiang Chan (Vientiane) and the Thai kingdom of Ayuthaya in their resistance against the Burmese. Down below is a modest museum with random artefacts donated by locals.
