History : The deity here resembles as the Lord is in Srivaikundam. Once Lord Brahma meditated on Lord Vishnu and got the Sriranga Vimanam, the pose of Lord Vishnu as He is in Srivaikundam. Lord Brahma was doing His Creation job only after worshipping the Sriranga Vimanam. Lord Surya’s grand-son King Ikshavagu worshiped Lord Bramha and brought the Sriranga Vimanam to Earth and placed in Ayodhya. The Surya Dynasty from King Ikshavagu to Lord Rama worshipped the Sriranga Vimanam. Lord Rama after Pattabishekam gave the Sriranga Vimanam to King Vibeeshana of Eezha (Lanka) Dynasty. While King Vibeeshana taking the Sriranga Vimanam to SriLanka, placed on the banks of River Cauvery & Kollidam. After some time when King Vibeeshana tried to unearth it , he couldn’t as Lord Vishnu has already given a boon to River Cauvery that Lord will come to Earth and wear her as a garland. Lord Vishnu appeared before him and told that Lord Ranganathar will be lying here and will be seeing the Sri Lanka from here. The Sriranga Vimanam was placed on the banks of Cauvery near Trichy and the ruler of Chola Dynasty at that time was King Dharmavarma. He was very happy and immediately built a small temple there for Lord Ranganathar and worshipped daily. When there was a flood in the Cauvery the temple went inside the Earth. From the heredity of King Dharmavarma came a King called Killivallavan, he while resting under a tree, a parrot advised him that the Lord Ranganathar is under this tree. He immediately unearthed the Sriranga Vimanam and renovated it and named the place as Sri Rangam.
