Sikkal is situated about five kilometers from Nagapattinam on the Nagapattinam-Tiruvarur route.Actually this is a Saiva temple with Lord Siva bearing the name Śrī Navaneetheswara. But the main deity is Lord Subrahmanya called Singaravelavar. Sage Vasishta made a sivalinga made of butter obtained from the milk of the divine cow Kamadhenu for worship. After puja, the sivalinga could not be shifted and got stuck and hence the name sikkal in Tamil for this place. This temple was worshipped by sages Vasishta, Viswamitra, wish-granting cow Kamadenu and Emperor Muchukunda of Deva Loka. Saints Sambandhar and Arunagirinathar have sung in praise of the Lord Sikkal Singaravelavar.
