The photos that follow are of the Buddhist temple Wat Xieng Thong.
Wikipedia: Wat Xieng Thong was built 1559-1560 by the Lao King Setthathirath near where the Mekong and Nam Khan rivers join. Until 1975 the wat was a royal temple under the patronage of the royal family and the Lao kings were crowned in the wat. The wat is considered as representing typical Laos art and craft.
