Encouraged by the zeal witnessed at the recent world classical Tamil conference, the DMK government has decided to fund an undersea expedition to excavate the remains of a 2,000-year-old town, Poompuhar or Kaveripoompattinam, submerged under the sea off the Nagapattinam coast in Tamil Nadu.
The marine archaeology wing of the Goa-based National Institute of Oceanography (NIO) will be assigned the task. The expertise of the underwater wing of the Archaeological Survey of India (ASI), which was involved in past explorations of the ancient sunken towns of Dwaraka and Mamallapuram on the east and west coasts, will also be used.
Reams and reams of ancient Tamil literature and even early geographers and historians like Ptolemy and Pliny have described the early Chola period town of Kaveripoompattinam as a vital maritime port that had trade links with the Roman empire and China until it was washed away by tidal waves, now recognised as a tsunami.
A few onshore and offshore excavations since the 1960s have given archaeologists an exciting glimpse of this once flourishing port town and capital of the Chola kings ring wells, brick structures, semi-precious stones and amphora pieces. Some artefacts and remains are displayed in the museum at Poompuhar town and preserved in the NIO.
Confirming the proposal, state minister for school education and archaeology Thangam Thennarasu told TOI that the government-sponsored excavation would be a significant step towards preserving Tamil culture. "We have initiated talks with the NIO and are exploring the scope of such an excavation, not just off Poompuhar but also other ancient ports," he said.

Underwater archaeologist Jon Henderson is hoping to reveal the secrets of the ancient Greek town of Pavlopetri.
A few metres under the sea, near the town of Neapolis at the southern tip of Greece, lies Pavlopetri. Discovered and mapped in the 1960s, it will become the first underwater town to be digitally surveyed in three dimensions. Nature News caught up with Jon Henderson, an underwater archaeologist at the University of Nottingham, UK, before the project began on 18 May.
What does Pavlopetri look like ? The site is submerged in about 3–4 metres of water, and covers an area of about 500 square metres, about 50-60 metres offshore.
There are about 15 buildings made up of three or four rooms, some streets, rock-cut tombs and courtyards — and there could be more underneath, because so far there has been no excavation. Some ruins date from at least 2800 BC, but we think the town Pavlopetri itself dates from the Mycenaean period, about 1600–1100 BC.
