Wat Si Saket is the oldest temple in Vientiane, and about the only building left standing after the Thais flattened the place (and stole the Emerald Buddha) in the 1820's. It's famous for having over 10,000 Buddha figures in every nook and cranny of the courtyard. It's also probably the nicest spot in the city, so let's move quickly on to Laos' most important religious center, and one of the ugliest Buddhist temples I've ever seen, Pra That Luang.
