The second precinct and the largest one of the temple houses a marriage hall and the chariot of the temple. The temple is one of the most visited temples in the district. The original animal mount of Murugan is believed to have been an elephant, compared to the peacock which is considered to be the most common mount. The white elephant, is considered a powerful, terror striking animal. The iconography is maintained only in two places, namely, this temple and Tiruttani Murugan Temple. Unlike other Murugan temples, where peacock is sported axial to the image of the presiding deity, an elephant is seen in front of Murugan in the temple.
