At a distance of 80 Kms from Thanjavur and 5 Kms from Nagapattinam (which is 85 Kms from Thanjavur), this temple is situated on Nagapattinam-Tiruvarur main road. The ancient history says here Lord Murugan got the 'Sakthi Vel' from Parvathi (refered as Velnedunkanni amman in this temple ) and killed Suran. This temple is one of the few temples in Tamilnadu which has both Siva and Vishnu in the same campus. The 'Vel vankuthal' festival in the Tamil month of Iyappasi is very famous here.
