A Shiva temple exists here, which was earlier a Vishnu temple. Once Agastya traveled south and reached Tirukkuralam (earlier name for Kuttalam) in the Tirunalveli district of Tamil Nadu. He saw a Vishnu temple there, but was forbidden from entering by the vaishnavas who saw Agastya’s ash smeared forehead. Agastya used his spiritual power to become a Vishnu devotee and entered the temple. To show the world that Vishnu and Shiva were different manifestations of the same concept and the greatness of Agastya, Vishnu turned the idol into that of Shiva. From then on, it remained a Shiva temple as per Skandapurana.
