Rameshwara means "Lord of Rama" in Sanskrit. According to Hindu epic Ramayana, Rama, the seventh avatar of the god Vishnu, prayed to Shiva here to absolve any sins that he might have committed during his war against the demon-king Ravana in Sri Lanka. Ramsetu Bridge is a chain of limestone shoals, between Rameswaram and Mannar Island, off the northwestern coast of Sri Lanka. The sea separating India and Sri Lanka is called Sethusamudram meaning "Sea of the Bridge". The Ramayana attributes the building of this bridge to Rama, naming it Sethusamudram which was built by the Vanara (ape men) army of Rama, which he used to reach Lanka and rescue his wife Sita from the demon king Ravana. This can be seen clearly from the air.
A visit to Rameshwaram is a must since it is one of the extreme points of India and it hosts a rich culture and heritage along with spectacular views.
