Anyone who is even remotely associated with India or has knowledge of Indian mythology or he or she believes in the legend of Lord Rama, the reference and existence of Ram Setu will not be alien to him or her.
The limestone shoals formed in a series extending about 48 kms, from India to Sri Lanka, is said to have been built by Lord Rama and his Vanara Sena in a bid to cross over to the country to fight Ravana for abducting Sita. The bridge was said to be completed in five days.
The formation starts just at the end of the Indian geographical boundary at Dhanushkodi, off Pamban Island near Rameshwaram in south Tamil Nadu. It reaches straight to Mannar Island of Sri Lanka and it has been scientifically established that centuries ago, the bridge could be crossed on foot, before a certain storm submerged a large portion of the bridge and disconnected it. Even today, the sea at most places is not more than a metre above the bridge and surprisingly, this causeway is visible from an aerial view even to this day.
The bridge finds first mention in the epic Ramayana written by Valmiki. Ramasetu and neighbouring areas like Rameshwaram, Dhanushkodi, Devipattinam and Thirupullani are mentioned in the context of various legends in Ramayana. Though there have been disputes, with certain scientific claims that the bridge was a natural formation, yet no one could provide a valid reason or substantiate the claims with any proof.
The doubtful antiquity of the bridge reaffirms the belief that Lord Rama was instrumental in getting the bridge built to cross over to Lanka on his rescue mission of wife Sita. Even the time of Ramayana (5,000 BCE) and the carbon analysis of the bridge sync properly, to corroborate the theory. Ramayana mentions that the Setubandha was constructed with floating stones. Surprisingly, such floating stones are scattered across Rameshwaram even to this day.
Thousands of devotees and tourists visit Ram Setu every year to experience the wonder of the great construction. One has to reach Dhanushkodi from Rameshwaram and from Dhanushkodi, parts of the Setu route are visible, whose starting point can be reached on foot. However, the road after Dhanushkodi needs government attention and turned into an all-weather motorable pathway so that people can drive their vehicles straight till the end of the Indian land and start of the bridge. Till date, it is a sandy and ill maintained road where only bikes can somehow travel or people can walk on foot which is inconvenient as the distance is tad more than what can be comfortably covered walking.
