Thiruvaiyaru is a place in India state of Tamil Nadu located at the longitude of 79.1049367 and the latitude of 10.8806531.
Thiruvaiyaru ? literally (in Tamil) the holy land of five rivers is about 15 Kms from Thanjavur. The five rivers are the tributaries of the Kaveri and form a sort of network around this town, giving it its name. The main temple here is to the lord who shares the name with the town ? Panchanadeeswarar in Sanskrit, or Ayyaarappan in Tamil. The story of how the temple came into being is an interesting one. A king?s chariot once got embedded in the ground. While digging around the wheels of the chariot to get it out, they chanced upon a lingam. A wise minister advised them to dig further, but carefully, and they were rewarded for their efforts with the idols of the goddess Dharmasamvardhini, Vinayaka, Muruga, and also a Nandi. To top it all, they also found a Siddhar (saint) deep in meditation underground. The saint advised the king to build a temple at the same place, and also told him to dig under the hoofs of the Nandi where he would find the wealth needed for building the temple.melattur
