Vat Phou is an ancient temple complex located in Champasak province in southern Laos. It is considered to be one of the most significant archaeological sites in Laos and is listed as a UNESCO World Heritage Site.

The temple complex is situated at the base of a mountain range and is believed to have been built between the 6th and 13th centuries by the Khmer Empire. The temple was originally dedicated to the Hindu god Shiva, but it was later converted into a Buddhist temple during the 13th century.

Vat Phou is composed of several structures, including two main temples, a palace, and several smaller buildings. The temples are built on different levels, and visitors must climb a series of staircases to reach the upper levels. The structures are made of sandstone, and the intricate carvings and intricate details showcase the skill of the Khmer Empire's stonemasons.

The temple complex is surrounded by lush green forests and is situated along the Mekong River, providing a stunning backdrop for visitors to enjoy. The site is also home to a museum where visitors can learn more about the history and significance of Vat Phou.

Today, Vat Phou is an important pilgrimage site for Buddhists, and it attracts both domestic and international tourists. The temple complex is particularly popular during the annual Wat Phou Festival, which takes place during the full moon in February and attracts thousands of visitors who come to witness the traditional ceremonies and performances.
