The Navagrahas with their consorts grace from the right side of the deity. Behind the deity is Adhi Koniamman and the shrines of Panchamuka Vinayaka, Lord Muruga with His consorts Valli and Deivanai.

The faith of the people in the city is that Mother Koniamman helps Her devotees in sweet conclusion of marriage proposals, they will get a child, diseases will be cured and ensure business development.

Of the three important temples of the city, Koni Amman temple is one. Mother Koniamman graces the devotees as one of the forms of Mother Parasakthi. She holds trident, Udukkai, sword, conch, scull, fire, discus, bell in Her eight hands. On the right ear she has the ear ring and a hanging ear ring on the left ear, called kundalam.

There are Neem, Vilwa, Nagalingam and Arasamaram as holy trees in the temple. This is the only temple Oonjal festival is celebrated during the 30 days of Aadi month – July-August. Every one in the city offers the first pooja for any auspicious functions in their houses as a mark of obtaining Her permission to proceed on. Car festival is celebrated only in this temple.

The place was a forest in days of yore. Kovan, head of the Irula community was ruling this region. He cured the place and developed it. The place was subjected to famine once and the suffering of the people was too severe. Irulan, praying to Mother, installed simply a stone and began worshipping it as a deity to protect his subjects. Mother yielded to his prayers, brought rain and prosperity. Irulas began to worship Amman as their family deity and built a temple.

The temple is on the southern side of the main city. Koniamman is the guardian deity of this place. After the end of the Irula rule, one Ilangosar became the ruler of the place when a Chera king invaded the city. To prevent his march, Ilangosar built a fort and a tall mud space, installed the Amman as the guardian deity. The Amman is being worshipped as Koniamman.

The temple is under renovation at a huge cost.
