Tirtagangga (holy water of the Ganges in Balinese) water garden was built in 1948 by the King of Karangasem, Anak Agung Anglurah Ketut Karangasem. This water garden was constructed in a very unique architecture of Balinese and Chinese styles.
The area of the watergarden is about 3 acres, consisting of three levels of ground stretching from east to west. On the highest northern Swah level there are the spring under the banyan tree, the upper swimming pool and two decorative ponds, one with four fountains reminiscent of Versailles, and the other with Victoria lotuses.
The first thing one sees when entering the garden is the elegant eleven-tiered Nawa Sanga fountain which rises from the middle of the complex. This fountain together with the two ponds form the middle Bwah level.
The larger lowest Bhur level, on the left side of the straight foot path running from the entrance to the west, is occupied by the big South pond with the long Demon island in the middle.
