This is considered as the Raagu sthalam for the Navagraha worship and was built by the descendents of Sekkizhaar (who wrote Periya Puranam). Here the Nagabharanam around the linga is supposed to be the Rahu for worship. The Nageswarar temple is more than 800 years old. The Lord is known as Nageswarar since he is being worshipped by Adi Sesha the foremost and king of all snakes and his consort is known as Kamakshi. This temple is believed to be built by Sekkizhar. This is considered the Raagu sthalam of the Navagraha Temples around Chennai. The temple and its tank are clean and well maintained. This place is also called as “Vada Thirunageswaram” i.e. temple similar to the Tirunageswarm temple near Kumbakonam.

The Thondai Nadu was divided into 24 sections and it was in the division known as “Puliyur Kottam” - Kundrathur - that Sekkizhar Swamikal was born. He was known as Arul Mozhith Thevar. Kulothunga II was ruling the

Chola dynasty at that time. He had heard the adage “Thondai vala nadu sandror udaithu”. The plentiful land of Thondai Nadu abounds with scholars. Kulothunga II realised the greatness of Sekkizhar and honored him with the title ‘Uthama Chola Pallavan.’ Sekkizhar became the minister of the King. He worshipped Lord Shiva in Then Thiru Nageswaram, near Kumbakonam. The temple tank is known as Surya Pushkarani since it has the distinction of Sun having his holy dip in it. The Champaka tree became the sthala vrksha, since Parvathi did her penance under the tree for uniting with her Lord in the ‘Ardhanareeswara’ form. Sekkizhar installed a Lingam in Kundrathur and consecrated a temple there, in all respects similar to the one in Then Thiru Nageswaram - with a temple tank called Surya Pushkarani and the Champaka tree as the sthala vrksha.
