Harihar (Kannada: ಹರಿಹರ, Harihara, [hʌrihər]) is a town located in Davanagere District in the Indian state of Karnataka. Harihar also spelled Hari-hara, in Hinduism, a syncretic deity, combining the two major gods, Vishnu (Hari) and Siva (Hara). Images of Harihara (also known as Sambhu-Visnu and Sankara-Narayana, variants of the names of the two gods) began to appear in the classical period after sectarian movements, which elevated one god as supreme over the others, had waned sufficiently for efforts at compromise to be attempted..The region of Harihar had been under the control of the Hoysalas from 11th to 13th Century AD. Harihar is famous for a Harihareshwara temple, which is also known as "Dakshina Kashi".
Harihara is situated on the banks of the Tungabhadra River, 275 kilometres north of Bangalore. The neighboring city Ranebennur is 22 km north west of Harihar across the river Tungabhadra. Harihar is connected by road and railway, and is located on national Highway 4 (Puna – Bangalore). It has a very pleasant climate through the year.
