Millions of devotees visit this place to protect themselves from the effects of the transit of Saturn. The greatness of the Thirunallur Temple is attributed to the unique idol of Lord Shani as he stands in the posture of blessing the devotee Abhaya Hast. This is a very rare phenomenon and therefore thousands of devotees who believe that they are badly affected by Shani visit the shrine to get his blessings.

The exact name of this Shani Temple at Thirunallar is Sri Darbaraneshwar Swaamy Devasthaan and it is also referred as Saneeswar Bhagavaan Temple. The main temple is dedicated to Lord Shiv. But the Shani Shrine has become more popular than the main temple primarily due to belief of devotees that by praying at the shrine will make Shani happy and thereby all the miseries and hardship are removed. Legend has it that King Nal mentioned in the Epics and Puraan was relieved of all sufferings after praying at this shrine. Believed to have been built in the 7th century, the temple also has small shrines dedicated to other gods including Lord Ganesh.
