Cambodia is a country in Southeast Asia, bordered by Thailand to the northwest, Laos to the north, Vietnam to the east, and the Gulf of Thailand to the southwest. Angkor Wat is a temple complex in Cambodia, located on a site measuring 162.6 hectares (1,626,000 m²; 402 acres) within the ancient Khmer capital city of Angkor1. It was built by King Suryavarman II during the 12th century as a Hindu temple dedicated to the god Vishnu1. The temple was gradually transformed into a Buddhist temple towards the end of the century. Angkor Wat combines two basic plans of Khmer temple architecture: the temple-mountain and the later galleried temple1. It is designed to represent Mount Meru, home of the devas in Hindu mythology. The temple is admired for the grandeur and harmony of the architecture, its extensive bas-reliefs, and for the numerous devatas adorning its walls1. Angkor Wat is the world’s largest religious structure, covering some 400 acres (160 hectares). It is also a UNESCO World Heritage Site.
