Hi Friends, So unfortunate were we that when we successfully hunted out this place, we found it locked. It seems that they open this only on few occasions or on some special request. There was no ASI board as well so no idea if this site is with ASI or not. Another thing is that I really do not know the site which I visited was in fact the same cave I was hunting for or some another shrine mistaken as a cave by me. As I have not seen the cave from inside, so this article is fully based upon the references. However there is an interesting legend of Murugan transferring his mount from elephant to peacock :). If anyone has been to this site before, please confirm if this is really Melacheri cave temple, as I do not want to put up something on net which might be wrong.
Thanks vj for confirming this, surprisingly I did not find a single plate for this site in A H Longhurst and K R Srinivasan's book except for the Shiva lingam of the cell. Was just thinking, those ASI people having all the support and capacities yet no picture. Thanks for the link, but sorry Tamil articles are of no use to me as unfortunately I do not know Tamil. Will see if I get any Tamil friend here who can do some translation for me :)
