Pha That Luang (Lao: ທາດຫຼວງ, IPA: [tʰâːt lwǎːŋ] 'Great Stupa') is a gold-covered large Buddhist stupa in the centre of the city of Vientiane, Laos. Since its initial establishment, suggested to be in the 3rd century, the stupa has undergone several reconstructions as recently as the 1930s due to foreign invasions of the area.
The architecture of the building includes many references to Lao culture and identity, and so has become a symbol of Lao nationalism. The stupa consists of three levels, each conveying a reflection of part of the Buddhist doctrine. The first level is 223 feet (67 metres) by 226 feet (68 metres), the second is 157 feet (47 metres) along each side and the third level is 98 feet (29 metres) along each side.
