Poompuhar Sunken City: New Discoveries and Tamil Nadu Travel Guide

Planning a trip to South India can be confusing when you want something more interesting than the usual tourist spots. You may be looking for beautiful beaches, lesser-known places and experiences that make your journey special. Poompuhar, a coastal town in Tamil Nadu, offers an interesting mix of seaside views, local attractions and a story that researchers are still exploring. Recent underwater surveys have brought fresh attention to this place, where archaeologists are searching for remains of an ancient port. But what has actually been found, and can you visit the underwater site? In this guide, KoiKoi Travel explains the latest discoveries, what visitors can explore on land, how to plan a trip and which nearby destinations you can add to your Tamil Nadu holiday.

What Is Poompuhar and Where Is It Located?

Poompuhar is a coastal town in Tamil Nadu, on India's southeastern coast. It lies near the place where the Kaveri River meets the Bay of Bengal. The town is also known as Kaveripoompattinam.

Poompuhar was once an important port. Today, visitors can explore its coastline and local attractions while learning about the archaeological discoveries connected to the area.

If you enjoy coastal destinations and places that are still being studied by researchers, Poompuhar can be an interesting stop on a Tamil Nadu trip.

Why Is Poompuhar Called the Sunken City of India?

Poompuhar is often described as a sunken city because researchers have found structures and other remains beneath the sea near its coast.

The town was once a busy port where people lived, worked and traded goods. Over time, changes to the coastline and the sea may have affected parts of the settlement.

However, it is important to understand that researchers are still investigating how much of the old settlement lies underwater and what caused the changes. The full picture is not yet confirmed.

The underwater discoveries make Poompuhar an interesting destination for travellers who enjoy learning about places beyond the usual sightseeing route.

What Are the Latest Underwater Discoveries at Poompuhar?

In September 2026, the Tamil Nadu State Department of Archaeology worked with the Indian Maritime University on an underwater exploration off the Poompuhar coast.

According to reporting by The Indian Express, the research team recovered pottery fragments, including a fragment of a vessel associated with long-distance maritime trade. Researchers also examined underwater structures and other possible archaeological remains.

The team used underwater survey equipment to identify areas that needed closer examination. The purpose was to understand the size of the old port, investigate possible shipwrecks and study changes in the coastline and river course.

These findings provide useful clues, but researchers still need to study the evidence before making firm conclusions about the site.

Can Tourists Visit the Sunken City Underwater?

Not as an ordinary sightseeing attraction based on the information currently available.

The underwater locations are being investigated by researchers. A confirmed public diving experience or visitor access to the archaeological sites has not been established by the sources used for this guide.

You can still visit Poompuhar on land, enjoy the coastal setting and explore local attractions. If underwater archaeology interests you, check for official updates before planning any special activity.

Do not book a diving trip based only on headlines about the sunken city.
