Pura Besakih or Besakih Temple is The Mother Temple of Besakih was built on the south slopes of Mount Agung, the principal volcano of Bali., in the village of Besakih on the slopes of Mount Agung in eastern Bali, Indonesia, is the most important, the largest and holiest temple of Hindu religion in Bali and one of a series of Balinese temples. Perched nearly 1000 meters up the side of Gunung Agung, it is an extensive complex of 23 separate but related temples with the largest and most important being Pura Penataran Agung. This is built on six levels, terraced up the slope. This entrance is an imposing Candi Bentar (split gateway), and beyond it the even more impressive Kori Agung is the gateway to the second courtyard.
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.
Besakih Temple is actually a complex made up of twenty-two temples that sit on parallel ridges. It has stepped terraces and flights of stairs which ascend to a number of courtyards and brick gateways that in turn lead up to the main spire or Meru structure, which is called Pura Penataran Agung. All this is aligned along a single axis and designed to lead the spiritual person upward and closer to the mountain which is considered sacred.
