Nong Bua Lamphu
Nong Bua Lamphu grew around a large lotus swamp on the Khorat Plateau. It was an important settlement of the Lan Xang world, with a community around Wat Si Khun Mueang already established in the reign of King Setthathirath. In 1574 the future Siamese king Naresuan passed through with an army on a campaign toward Vientiane. The town was damaged and abandoned during the war between Siam and the Lao ruler Anouvong in 1826–27.
