Thirukkoodalur is one of the 108 Abodes of Lord Vishnu (108 Divya Desams), which is situated at about 12 kms from Tiruvaiyaru on the Tiruvaiyaru-Kumbakonam road in Tamilnadu. This is also called as Aaduthurai Perumal Koil or Sangama Kshetram. Thirumangai Azhwar has sung in praise of the Lord here.

This temple is where the Devas have congregated to worship Lord Vishnu and prayed him to save Earth from Demon Hiranyakshan. Hence the reason for Lord Vishnus incarnation or Avtar - Varaha Avatar. The place is called Thirukkoodalur as the Devas have come together to pray Lord Vishnu. (Koodal means coming together). There is also a legend that says that an estranged wife of a Chola King who was an ardent devotee of the Lord here was united with her husband, and hence the name Thirukkoodalur.

Lord Jagatrakshaka Perumal has given darshan to Devas, Saint Nandaka, King Ambareesan, Thirumangai Azhwar, Brahma the Creator and the rivers Ganga, Yamuna and Saraswathi at this place. When River Cauvery prayed Lord to wash away the sins given by all the others by taking bath in the river, Lord said that she should flow near His Shrine at Thirukkoodalur. Thus the sins of Cauvery were washed away.

The sthala vriksham or Holy Tree here is Palaa (Jack fruit tree). When an attempt was made to cut a part of the tree for carrying out renovation work, a natural formation of a big conch was found on the trunk of the Jackfruit tree. Pilgrims throng the temple now for witnessing this Conch formation.

Renovation and restoration work estimated to be around US $150,000 was completed and the last Mahasamprokshanam was held in June 2003.
