Alagunachi Amman Temple constructed in the 16th is located 80 km away from Pollachi. The temple was built by some people from Valliarachal. The main deity of the temple, Alagunachi Amman is the clan god of the Kongu Vellala Gounder community.
It is believed that some people from the clan had come to the clan with an idol of their god which had disappeared while they were resting. So the group decided to build a temple and stay in the area, while taking care of the temple.
