Touted as one of Southern India’s biggest forts, the Vattakottai Fort sprawls over 3.5 acres of area and is a must to be seen in your lifetime. The most intriguing feature of this fort is its location which is just on the shore of the majestic Bay of Bengal. History buffs too will have loads to discover and study when they come here, particularly the architecture. There is a lighthouse in ruins very close to the fort. It is perfect for shooting pictures.
