Mr. Pradeep is an avid Heritage enthusiast and writes regularly for the Hindu on temples. He also speaks at many forums on art, culture and Heritage of our land. He has written a book on Thanjavur, which is expected to be released in early 2010.
I have included below a mail from Pradeep Chakravarthy. He is organizing a heritage walk around Velachery. Let him know if you are keen to join.
