Poompuhar was at one time the greatest port on the east bank of Tamil Nadu, and was as its pinnacle of eminence under the prior Chola rulers. The River Kaveri is converging with the ocean here. It was known as puhar because of the impeccable magnificence of the port town, and it later came to be called Poompuhar. Silappathikaram and Manimekalai, the tamil sagas, draw out the enormity of the city in a portion of the ballads in Sangam writing. Danish Fort that was worked as right on time as 1620 A.D is the magnum opus of the Danish engineering in India. The fortification is in consummate condition till now and the greater part of the beautifications and carvings are as yet unmistakable. A fine shoreline and quiet waters offer great open door for sunbathing and swimming.
