The temples here are as follows
Sri Ramanathaswamy Temple: According to a legend, the Lingam at this temple was installed by Sri Rama. On His return after the battle of Lanka, Rama wanted to install the Lingam to absolve Himself of the sin of vanquishing Ravana. Rama sent Hanuman to Mount Kailash to fetch the Lingam. Since Hanuman was late, Sita made a Lingam out of sand. This was installed as Rama Lingam and the worship was over.
Meanwhile, Hanuman rushed in with the Lingam from Kailash. He was disappointed to find another Lingam already in place. To pacify Hanuman, Rama had the Hanumath Lingam (Viswa Lingam) also installed alongside and ordered that the puja be first performed for the Viswa Lingam. That tradition is being followed even today.
The shrine of Parvathavardhini, consort of Sri Ramanatha, is to the right of Rama Lingam. A Sri Chakra can be seen here. There is a separate Vishnu shrine dedicated to Sethu Madhava. There are shrines for Pallikonda Perumal, Santhana Ganapati, Ashta Lakshmi, Nataraja and Hanuman.
