The Pura Ulun Danu of Nusa Ceningan is dedicated to Dewi Batari Ulun Danu, goddess of the lakes and rivers. This temple is situated on the western part of Nusa Ceningan, one of the three sister islands that are located just off the coast of South-East Bali. This Ulun Danu temple is also known as 'the Temple of the Cave', as it is built on a hill top which covers a holy cave, the Goa Raja or "King's Cave".

Placed on a concrete platform in this temple is a small ship, flanked by the statues of Dewa Baruna, god of the seas, and Dewi Ayu Mas Segara, goddess of the Southern Seas - in Java commonly known as Lörö Kidul.
