Five Vaishnava temples

Ramanuja traveled eastward and came to Tondanur, the second capital of the Hoysala Empire. Bitti Deva (Vittala Devaraya) was the name of the Hoysala ruler. His daughter was suffering from a mental illness. He cured the illness of the princess, to the delight of the king. He was drawn to Ramanuja's faith and became a Srivaishnava. He then onwards came to be known as Vishnu- vardhana. In memory of this great event, the king built five Vaishnava temples

1. Channiganarayana temple at Belur,
2. Nambinarayana temple at Tondanur,
3. Kirtinarayana temple at Talakad,
4. Veeranarayana temple at Gadag and
5. Chaluvanarayana temple at Melkote.

These temples are lasting monuments of Karnataka culture and architecture. Ramanuja built many other temples too in Tondanur. He also got constructed a huge reservoir called ‘Tirumalasagara'(now called Moti Talab).
