Swayambhunath is an ancient religious architecture atop a hill in the Kathmandu Valley, west of Kathmandu city. According to Swayambhu Purana, the entire valley was once filled with an enormous lake, out of which grew a lotus. The valley came to be known as Swayambhu, meaning "Self-Created." The name comes from an eternal self-existent flame (svyaṃbhu) over which a stupa was later built. Swayambhunath is also known as the Monkey Temple as there are holy monkeys living in the north-west parts of the temple. The stupa consists of a dome at the base, above which is a cubical structure painted with eyes of Buddha looking in all four directions. There are pentagonal Toran present above each of the four sides with statues engraved in them. Behind and above the Torana there are thirteen tiers. Above all the tiers there is a small space above which the Gajur is present.
