There are three different sannidhis (Three temples) in this temple complex. As we enter,the first sannidhi is that of Sankar and the second one is that of Shankarnarayan and third one is of Gomati (Parvati).
This is the place where Goddess Parvati, known here as Gomathi Amman had performed a penance to have the darshan of Vishnu and Siva in unison. She performed the tapasu in the month of Aadi which is an auspicious month for the south Indians. Both Vishnu and Siva appeared before her in unison called Shankar Narayan. The deity here is half Vishnu and half Siva and this can be easily distinguished by the costume that is adorned to the deity. One onside it is tiger skin cloth and ash on forehead representing Siva and on the other half it is white cloth and the Tirunamam which is typical of Vishnu.
Inside the Gomathi Amman temple there is a place where devotees can take Puttruman ( i.e. Holy sand of ant hill as a prasadam. The general belief is that the Holy Sand- "Puttruman" is capable of curing all the diseases. Devotees believe that Sankarankoil‘s Nagasunai (sacred tank) have been dug by serpent kings named PadumanSangam which has a miraculous power to heal those who bathe there. It is believed that all devotees who pray to the goddess Gomati Amman get her divine blessings . As it is festival time during the month of Aadi this temple gets crowded with pilgrims. and
This temple is held sacred by both vaishanavites and Saivites as it a fine example to depict that both Vishnu and Siva are same. Another legend associated with the temple is that once there was a quarrel between and Shaivites, the followers of Siva and Vaishanavites, the followers of Vishnu as to who is the greater god. To put all notions of people at rest to show that both Vishnu and Siva are same , both Gods appeared before their devotees in unison one half representing Siva and other half as Vishnu.
