Perched 3,000 ft. up the side of the volcano Gunung Agung is Bali's most important temple, Pura Besakih. It is an extensive complex of 23 separate-but-related temples. The stone bases resemble megalithic stepped pyramids, which date back at least 2000 years. It was used as a Hindu place of worship from 1284, when the first Javanese conquerors settled in Bali.
