Angkor Wat is a large Hindu temple located in Cambodia that was built in the early 12th century by the Khmer civilization. It was originally dedicated to the Hindu god Vishnu but is now a Buddhist temple. The reliefs on the walls depict stories from Hindu and Buddhist mythology, including the Churning of the Ocean of Milk and the Battle of Lanka between Rama and Ravana. Angkor Wat was built to honor the memory of King Suryavarman II and was the largest religious structure of its time.
