Among the riverine major ports in India, the oldest port having been in existence for more than 100 years is Kolkata Port.
– Kolkata Port (now Syama Prasad Mookerjee Port) is located on the Hooghly River, a distributary of the Ganga. It is a riverine port. It is one of the oldest major ports in India, with operations tracing back to the era of the British East India Company in the late 17th century. It became a major port well over 100 years ago.
– Cochin Port is located on the Arabian Sea coast, not a riverine port.
– New Mangalore Port is located on the Arabian Sea coast, not a riverine port. It was commissioned in 1974.
– Paradip Port is located on the Bay of Bengal coast, near the confluence of the Mahanadi river and the sea. While it’s near a river mouth, it’s an artificial deep-water port built in the 1960s, much younger than Kolkata Port.
Kolkata Port is India’s only major riverine port. Its history is deeply intertwined with the colonial era and trade routes to Eastern India. Its long history clearly satisfies the condition of being in existence for more than 100 years.
