Pura Ulun Danu Batur ("Head of the Lake") with obvious Indian influences. This is one of the most significant religious complexes on Bali. Lake Batur is the source of dozens of underground springs, which help regulate the flow of water for the farmlands and sacred pools throughout the whole south-central region. Farmers from all over the island pay homage here to Ida Batari Dewi Ulun Danu, the life-sustaining and highly venerated goddess of the lake, who supplies the 37 rivers, tributaries, dams, and irrigation canals between here and the sea with water.
The nine-temple complex, with its impressive tall gateway, contains a maze of 285 shrines and pavilions dedicated to the deities of water, agriculture, holy springs, and arts and crafts. The largest temple, Pura Penataran Agung Batur, consists of five spacious well-swept black-gravel courtyards filled with rows of thatched-roof meru towers. The 11-roofed meru in the inner courtyard is dedicated to Dewi Danu, the goddes of the lake.
