About
About Poompuhar – Sangam Drowned Port of Kaveripumpattinam
Poompuhar, Sangam capital of Early Chola and legendary Manimekalai port, preserves a 1.5 km drowned wharf district 100 m offshore at –2 to –4 m and a buried warehouse quarter 1 km inland under dunes. NIO sonar and Tripathi diving (1990–2005) mapped brick wharf with mooring posts at –2.5 m, ring-well drains, amphorae and Roman Rouletted ware at –3 m 500 m offshore, and submerged U-shaped stone structure (breakwater) 120 m long at –4 m. Sangam poems Pattinappalai and Manimekalai describe sea-swallowed Puhar after flood; radiocarbon dates 4th c. BCE–4th c. CE overlap Kaveri delta progradation. Offshore cores show beach-ridge silt sealing urban layer 2 m thick.
Why it mattersOnly Sangam drowned port archaeologically mapped; wharf–breakwater complex anchors Tamil–Rome trade and Kaveri delta progradation.
