History of Pattanam
Periyar Thodu or the Periyar canal, which is a branch of the Periyar River flows through an area which is close to Pattanam. However, some geologists have discovered with the aide of satellite imagery that the delta of Periyar River was existent on the southern side and that this Indian river might have flowed near Pattanam. Besides this, the regional inhabitants of Pattanam have unearthed a vast quantity of broken pottery shards and old fired bricks, when they were digging the ground. All such evidences clearly suggest that the Periyar River might have probably flowed near Pattanam 2000 years ago.
