About
About Korkai – Early Pandyan Drowned Port, Tuticorin
Korkai, early Pandyan pearl-fishery capital on Tambraparni mouth, preserves a silted harbour now 8 km inland at 3 m asl, with buried beacon mound (korai) and salt-pan wharf traced by cores as harbour mud 2 km south of modern Thoothukudi. ASI–NIO coring (Kumar 2010) identified 3 m harbour silt with 3rd c. BCE Megasthenes-period black-and-red ware and pearl oyster middens, plus 4 m-high brick warehouse platform now pasture. Periplus 58 and Sangam Akananuru describe Korkai as pearl entrepôt; after 1st c. CE Tambraparni shift silted basin, harbour moved to Kayal. The mound's brick stratigraphy 4th c. BCE–9th c. CE anchors delta silt hourly curve.
Why it mattersOnly Early Pandyan pearl harbour with intact midden stratigraphy; cores anchor Gulf of Mannar pearl trade and Tambraparni delta chain.
