Keeladi and Other Archological Sites of Tamilnadu (Paperback) (ISBN-13: 9781637143117)

Tamilnadu had a unique civilization unique in the sense, it was the most chaotically recorded civilisation in the history of the whole India. For a very long time, the tiny tail-like part of the Indian subcontinent was about of bounds for most of the invaders beyond the Vindhya -Sathpura hill ranges. This hill range cuts the Indian subcontinent into two Uththarapada ( Northern part )and Dakshinapada ( southern part) except for a linear vertical strip of land in the west and east along the coastline.
