Nagara Koil:

Nagara Koil: The people of Chettinad moved on from their settlement to other villages not far from their first settlement and, there were nine main clusters of villages. To each of them the Pandya King granted a temple in perpetuity. The nine temples thus became the family temple for each group and each cluster evolved as a subdivision of the Chettiars or what might describe as a fraternal clan. The clan temple tradition is that a wedding is recognized only if the bride and bridegroom receive wedding garlands from their respective clan temples. The moment the wedding is registered, the bridegroom becomes a pulli.

Ilayathangudi: The first of the clan temples was in Ilayathangudi and it is 25 kms from Karaikudi on the road to Kunrakudi, passing Nemam, Keelasivalpatti and Avinipatti on the way. It is said to have been granted to the Nagarathars in 707 A.D. The temple is known for its great sculptural value and it has the biggest tank, "oorani" of all other temples. Legend has it, that this was the resting place of the gods and it explains the village's name with a syllable break-up that is as follows: ilaippu meaning tiredness, attru meaning to remove and gudi meaning place.
