Angkor Wat is a Hindu-turned-Buddhist city-temple in Siem Reap, Cambodia. While the world might know of it as Angkor Wat, it was, sadly, a misreported name by a french reporter. The name Angkor has no meaning in Khmer, the language of the Cambodian people, and it's actual name was Nokor Wat.
The origin of Nokor Wat's design is representative of Mount Mandara, the famous mountain used to churn the Ocean of Milk in the famous Hindu story of Samudra Manthan. In this story, the Hindu Gods and Demons agree to churn the Ocean of Milk with the Naga, a giant serpent, wrapped around the mountain to spin it and produce the elixir of immortality. Throughout not only Nokor Wat, but the entirety of Siem Reap, you can find Gods and Demons pulling the Naga in a tug-of-war fashion, depicting the epic.
