The Ulun Danu Beratan Temple is a significant temple complex located on the western side of the Beratan Lake in Bedugul, central Bali. Ulun Danu Beratan, literally ‘the source temple of Lake Beratan’. The temple was built in the 17th century in worship of the main Hindu trinity, Brahma-Vishnu-Shiva, as well as the lake goddess, Dewi Danu. The history of the Ulun Danu temple can be traced back to the rise of the Mengwi kingdom. The ‘floating’ temple complex is comprised of four groups of shrines, including the prominent Lingga Petak shrine to its east. There are four gates facing each of the four points of the compass. The second group is located in the west and pays homage to another temple in the hill of Puncak Mangu and is regarded as the symbol of soil fertility. The ‘puncak’ or hilltop of Mangu is northeast of Lake Beratan.
