Kānchi, also known as Kanchipuram, was an eminent cultural and political center in ancient South India. It was under the rule of the Pallavas who promoted trade and commerce extensively. To facilitate inland trade, Kānchi had an inland riverine port at Nrapeyuru. This port played a crucial role in transporting goods from inland areas to coastal ports and vice versa, enhancing Kānchi’s connectivity to broader maritime networks.
Nrapeyuru is mentioned in ancient Tamil inscriptions and historical texts as an important inland trade center associated with Kānchi. This link between urban centers and riverine ports was significant for economic growth during the early historic period in Tamilakam.
