The Marudu brothers of Sivagangai associated with Kalayar Kovil have made several contributions to this temple. The hilly village includes five areas (Piranmalai Main, Mathagupatti, Pudupatti, Pappapatti, Adiyarkulam).

Piranmalai is said to have been ruled by Paari Vallal. Piraanmalai is said to be a block of Mount Meru, which got blown off during a fierce tussle between the serpent king Aadiseshan and the wind God Vaayu(as in Tiruchengode). Since this hill is in the form of a Sivalingam, it is also called Prachandragiri and Katoragiri. Bhrama, Saraswati, Subramanya and Nandi are believed to have worshipped Shiva here.
