With very contemplative ambience, probably the oldest standing temple in Vientiane and among the most atmospheric. Built in 1818 by Chao Anou in the Bangkok-style and hence left unsacked when much of Vientiane was razed in a Siamese raid in 1828. Within the cloister walls are hundreds of niches housing Buddha images large and small, made of wood, stone, silver and bronze. In the centre of the courtyard is a five-tier-roofed sim (ordination hall) housing yet more Buddha niches and beautiful, but fading murals of the Buddha's past lives.
