One road leads to Gangaikonda cholapuram towards east. One road lead to Trichy towards west. Third Road towards Thiruvaiyaru Thanjai.
MELAPPAZHUVUR :: 3 KMS WEST OF KEEZHAPPAVUR on the Trichy Road.
ON THE MAIN ROAD itself the Temple Avani Gandharva iswara Griham - which was brought under State Archeology monument by Dr. nagaswamy - which we saw together last Nov, which is the subject of discussion here - which SRB has described and you highlighted - is located.
THIS PLACE IS KNOWN AS KEEZHAIYUR being the Eastern border of Melappazhuvur.
Another one KM farther down, in MELAPPAZHUVUR there is another ancient Siva temple.
Yeah... There are 3 sites. Kilappazhuvur - Melappazhuvur and in-between Keezhaiyur.
Will post the inscriptions re Avani Gandharva iswara griham next week.
