This place is about eight kms from Nagpattinam towards Tiruvarur. The Moolavar is Sri Loganathan also known as Neelameghavannan in standing posture facing east and the Thaayar is Sri Loganayaki. The legend is Sage Sri Vashista had a practice of making a Sri Krishna Vigraham out of butter, which he would then use for worship. One day Sri Krishna came in the form of a small boy and ran away with the butter.
Sri Vashista chased the boy but later came to learn that this boy was Lord Sri Krishna. He then prayed and at this place a big temple appeared in the presence all the Devas. Since Sri Kannan came to this place as a boy this place came to be known as Thiru Kannangudi.
Normally in all Vaishnava temples the idol of Garuda will show his folded hands in a prayer form; in this temple, however, he is in a dasya form with his hands tied. This is the form of Garuda at Vaikuntam. In this temple there is a festival known as "Thiruneeruanivizha" during which, the Perumal's forehead is smeared with viboothi. The devotees also come with viboothi on their foreheads. Thiru Mangai Azhwar has sung in praise of this Lord.
