Radio jockeys and scribes are seeking celebrities for quotes on why Madras is special. They also depend on historians for facts and figures related to erstwhile Madrassapattinam. But one part of Madras is neither reported nor documented. Kosapettai, Pudhupettai, Chindatripettai, Vannarapettai, Saidapettai, Kanamapettai, Krishnampettai and Tondiarpettai are often forgotten though these pettais have unique identities and for centuries have been hubs for specialised trades. These are the places that really allowed cultural and ethnic diversity to spread when the coastal town expanded as city.
