That Luang, or the Great Stupa, in Vientiane is a national symbol (its image is on Laos’ official seal) and also the most sacred monument in the country. From the outside That Luang looks more like a fortress surrounded by high walls and it features two temples with the main stupa, the top of which is covered with gold leaf, standing 148 feet tall. The beautiful architecture is in Lao style, influenced by Buddhist beliefs – these include finely-gilded, red-lacquer doors, pointed lesser stupas, many Buddha images and beautiful flower and animal images.Locals say that it was originally built as early as the third century to house a breastbone of the Lord Buddha brought to Laos by an Indian missionary. However, the current structure was built by King Setthathirat in 1566 on the site of a 13th century Khmer ruin. He named Vientiane the capital after Luang Prabang in the mid-sixteenth century. An elegantly crafted statue of him stands in front of the main entrance to That Luang.
