Wat Phu 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.
Wat Phu is linked to the Shrestapura, which is located directly on the Mekong River in the east of Lantaravatta (now called Phu Kao). At the end of the 5th century, the city was the capital of the realm of texts and inscriptions related to Chenla and Champa. The first structure on the hill was built now. This mountain is important for the spiritual significance of the Elizabethan protein on the top of the mountain. This mountain is considered the home of the universe and the river that represents the sea or gang. The temple was dedicated to the Father by nature, while the spring water behind the temple was considered sacred.
Vat Phu was part of the Khmer empire centered on Angkor in the south, during the reign of Yasovarman I at the beginning of the 10th century. Shrestapura was replaced by a new city in the Angkor, directly in the south of the temple. Over time, the original building was replaced by some stones. The temple was seen to have been built mainly during the Koh Ker and 11th-Century Middle Ages. Little changes were made during the next two centuries before the temple, like most of the empire, was transformed into Theravada Buddhism.
This continued after the area was under Lao law and a festival was held on this site every February. Small repairs work have been done besides repairing border posts. Vat Phu was considered a World Heritage Site in 2001.
