Vat Phou (or Wat Phu; Lao: ວັດພູ [wāt pʰúː] temple-mountain) is a ruined Khmer Hindu temple complex in southern Laos. It is at the base of mount Phou Khao, some 6 kilometres (3.7 mi) from the Mekong in Champasak Province. There was a temple on the site as early as the 5th century, but the surviving structures date from the 11th to 13th centuries. It has a unique structure: The elements lead to a shrine where a lingam dedicated to Lord Shiva was bathed in water from a mountain spring. The site later became a centre of Theravada Buddhist worship, which it remains today.
