Mother Temple of Besakih
The biggest and oldest temple on the island is Pura Besakih. It is an immense sprawling complex that features amazing views and temples. From Wikipedia:
The precise origins of the temple are not clear but it almost certainly dates from prehistoric times. The stone bases of Pura Penataran Agung and several other temples resemble megalithic stepped pyramids, which date back at least 2000 years. It was certainly used as a Hindu place of worship from 1284 when the first Javanese conquerors settled in Bali. By the 15th century, Besakih had become a state temple of the Gelgel dynasty.
