Legends: Bhrama and Vishnu worshipped Shiva, hence the name Trimurthy Kovil. Agasthyar also worshipped here. In a test of strength between Adiseshan and Vayu, the five gems from the head of Adisesha were scattered. A red stone landed at Tiruvannamalai, an emerald at Eengoimalai, a blue diamond at Potikai, a manikkam at Vaatpoki and a diamond here. The Vinayakar here is called Kaviri Kanda Vinayakar.
Temple: This is a vast temple with grand shrines to Kodumudi nathar, Vadivudaiammai and Perumaal and Taayaar. This temple has three entrances leading to the three shrines.
