The small hamlet of Keezhadi in Sivaganga district near Madurai in the state of Tamil Nadu recently got its share of international recognition as it became a site of historical importance. A number of square-shaped trenches were dug out by the Archaeological Survey of India (ASI) to reveal what archaeologists believe to be the largest human settlement of Sangam Age, apparently dating back to 3rd century BC, nearly 2,500 years ago.
