The Ranganthaswamy Temple - usually referred to as Sri Ranganathaswamy - is dedicated to Ranganatha, a manifestation of Vishnu. It is one of the five important pilgrimage sites along the river Kaveri for devotees of Ranganatha. These five sacred sites are together known as Pancharanga Kshetrams in Southern India. Since Srirangapatna is the first temple starting from upstream, the deity is known as Adi Ranga (lit; first Ranga), and the town of Srirangapatna, which derives its name from the temple, is on an island in the river Kaveri.
