MADURAI, INDIA, May 29, 2016 (Times of India): With structure after structure surfacing from under the soil, the massive scale of an ancient urban centre that lies buried at Pallisanthai Thidal in Sivaganga district of Tamil Nadu is emerging. The second phase of the work undertaken by excavation branch VI, Bangalore, of the Archaeological Survey of India suggests that the settlement at Keeladi village could be as large as the ones in Harappa and Mohenjo Daro [though much later in time, 300 bce compared to 2100 bce-the article’s headline about “Harappan” is rather misleading]. The excavations reveal a well-built urban center with many amenities.
After exploration works on the Vaigai riverbed in 2013-14, the office of the superintending archaeologist, excavation branch VI in Bangalore, shortlisted Keeladi village for excavation. The first phase of the study carried out in 2015 unearthed various antiquities, iron implements and earthenware, both foreign and locally made. The pot shreds of Arretine dating back to 300 bce proved foreign trade existed in the region during the period.
