Tirta Gangga literally means water from the Ganges and it is a site of some reverence for the Hindu Balinese. Strictly, the name refers to the water palace built in 1948 by the Raja of Karangasem, Anak Agung Agung Anglurah Ketut Karangasem. It is, however, the name widely used to refer to the general area which includes the water palace and the lush rural areas around. Tirta Gangga water palace is a maze of pools and fountains surrounded by a lush garden and stone carvings and statues. The one hectare complex was built in 1946 by the late King of Karangsem but was destroyed almost entirely by the eruption of nearby Mount Agung in 1963. It has been lovingly re-built and restored and has an air of authentic royal magnificence.
The centrepiece of the palace is an eleven tiered fountain and there are many beautiful carvings and statues adorning the gardens. The area around Tirta Gangga is noted for its rice paddy terraces.
