Situated on the banks of River Cauvery, this town lies on the outskirts of Thanjavur. The main attraction is Panchanatheeswar Temple that is dedicated to Lord Shiva. Surrounded by lush paddy fields and groves, the temple has a very serene atmosphere. Devotees can also take a dip in the Cauvery river here, which is believed to absolve one of their sins. Another attraction is Thiruvaiyaru Temple, which is one of the seven temples called Sapta Staanam. This temple is associated with the wedding of Nandi (bull god), the mythical vehicle of Lord Shiva.

Thiruvaiyaru is recognised as the place where one member of the trinity of carnatic music, Saint Thyagaraja lived and attained samadhi. The best time to visit the temple is during a music festival held every January to commemorate the birthday of the saint.
