The presiding deity is Lord Shiva. The shivling was consecrated under the Kiluvai Tree by Chinnaiyan, who later in life came to be known as ‘Ayyan’ - a devotee of Lord Shiva. Adjacent to the linga is an ant-hill, the soil of which is given as prasad to the devotees. The soil if applied all over the body is believed to cure the ill effects of poisonous insect bites.
