Pura Ulun Danu Bratan is a major Hindu Shaivite temple located on the shore of Lake Bratan in Bali, Indonesia. Built in 1633, the temple is used for the ceremony of offerings to the Balinese water, lake and river goddess Dewi Danu, due to the importance of Lake Bratan as a main source of water for irrigation in central Bali. The temple is laid out with three courtyards separated by low walls pierced by ornate gateways. The inner courtyard houses the shrines, which are square structures with brick bases and multiple pagoda-style thatched roofs, the number of roofs reflecting the status of the deity; it is always an odd number, and the eleven at this temple indicate the importance of Dewi Danu.Photograph credit: Uwe Aranas
