Vat Phou or Wat Phu is a ruined Khmer temple complex in southern Laos. The temple has a unique structure, in which the elements lead to a shrine where a linga was bathed in water from a mountain spring.
Wat Phu or Vat Phou (meaning ‘mountain temple’) is a ruined Khmer Hindu temple complex located at the base of mount Phu Kao on the West bank of Mekong River. It was built under the Khmer Empire and is considered one of the oldest archaeological sites in Laos. One temple in the site was constructed around the 5th Century but most buildings found in the complex are from the 11th to 13th centuries. Like other notable Khmer architecture in Southeast Asia, it was constructed using sandstone, laterite and bricks. Wat Phu was designated by UNESCO as a World Heritage Site in 2002
