Possible Sangam-Age Irrigation Structure Found on Kollidam River in Tiruchi
Archaeologists from the Archaeological Survey of India (ASI) have identified brick structures exposed on the Kollidam river bed near Koogur in Tiruchi district as likely remnants of a Sangam-age irrigation system dating to the 3rd-4th century CE. The structures include a semi-circular brick wall and submerged parallel walls, possibly forming an inlet or outlet channel for water regulation. Found near the ancient Kallanai dam, these remains suggest early historic water management techniques in the region.
