Vishnu Temple of Srirangam is located on a small island between branches of the rivers
Cauvery and
Coleroon. The most revered of the 108 pilgrimage shrines of
Vishnu, and the largest temple complex in all India, it is surrounded by seven concentric walls and 21
gopurams. Vishnu, the second deity of the trinity of Hindu gods, is responsible for the nourishment, protection and maintenance of the universe. Many saints and sages have spent their time at
Srirangam, including the 11th century sage Ramanuja. Srirangam is also listed as one of the
Navagraha sthalas (temples representing the planets).
