As per Hindu legend, this is one of the 64 places where Shiva performed his Thiruvilayadal, the divine plays. A dancing girl named Ponanaial was a staunch devotee of Shiva and her only aim in life was to make an idol of Shiva made of gold. She was not able to accomplish due to lack of money. Pleased by her devotion, Shiva appeared in the form of metallurgist named Rasavathi who converted iron, bronze and aluminium to make the golden idol. Impressed by the beauty of the idol, Ponanaial pinched the cheeks of the idol, which is believed to be the mark in the idol. The lingam in the temple is believed to have been self-manifested and was worshipped by Surya, Dharmaraja, Nala, Chandra, Thirasanan, Brahma and Vishnu. Since Shiva appeared under Parijatha tree, the presiding deity came to be known as Pushpaveneswarar. Architecture
