A joint team of marine archaeologists has located the submerged remains of a massive Roman-style trading hub off the coast of modern-day Tamil Nadu. Using high-frequency sonar and robotic divers, the team identified a series of stone jetties and warehouse foundations that align with early Roman architectural standards. The site has yielded several amphorae of Mediterranean wine and a unique lead-lined chest containing silver Denarii and fragments of East Asian silk, confirming the location as a critical node in the trans-continental spice and silk trade.
The discovery provides the first physical evidence of a permanent Roman commercial presence in the Bay of Bengal. Previous evidence was largely limited to stray coin finds and literary accounts, but the scale of this port suggests a sophisticated, multi-generational trade operation. Researchers believe the city was submerged due to a catastrophic seismic event in the 3rd century CE, which inadvertently preserved the site in an anoxic environment beneath the seafloor.
