The Ancient city of Poompuhar was once a flourishing port city known as Kaveripattinam,which for a while served as the capital of the early Chola kings in Tamilakkam.
Located on the mouth of the Kaveri river, much of the town was washed away by a powerful sea storm in 500 AD.
Later pottery dating back to 4th and 5th century was discovered on the shore of the town.
