As per the Legend, Lord Indra Killed the demon Kartaba with the weapon (Vajrayudha) made out of Sage Dadichi’s spinal cord. In revenge for his father’s death, demons Pippala and Aswatha conducted a war. Sage Agasthya and others approached Saneswara for the defence. Sages offered their divine power to Shani Bhagawan. The battle between the demons and Shani went for a year and killed them at the end. Saneswara Bhagavan installed and worshipped Lord Siva to get rid of Brahma Hatya dosha.

It was mentioned in the Markandeya Purana that whoever performs Thailabhishekam for Siva at this temple will be relieved from Shani Dosha.

Sage Gouthama installed Venugopala Swamy as the Kshetra Palaka.
