Sri Parimala Ranganathaswami temple located on the banks of the River Cauvery is one of the 108 temples of Vishnu (Vaishnava thirupathis or divya desams) revered by the vaishnavite poets, the Alwars. Sri Parimala Ranganathaswami an incarnation of Lord Vishnu is personified in this temple in a 12 foot idol made of green stone. Lord Vishnu’s consort Parimala Ranganayaki is variously known as Chandra-shapa-vimochanavalli and Pundarikavalli. Legends holds that the Goddess absolved Chandra of his curses at this holy site, hence the name Chandra-shapa-vimochanavalli. The temple although significant by itself, is a part of a religious pilgrimage circuit called the Pancha Ranga Kshetram. The Pancha Ranga Kshetram literally translates as the five Vishnu temples.
The temples follow the course of the river Cauvery, beginning with Sri Ranganathaswami temple in Srirangapatnam, Sri Ranganathaswami temple in Srirangam, Sarangapani temple in Kumbakonam, Sri Appakkudathan temple in Trichy and finally Sri Parimala Ranganathaswami temple in Mayiladuthurai.
