It is said that Pilgrimage to Kashi will be completed only after the worship at Rameswaram besides a holy bath in Dhanushkodi at the Confluence of Mahodadhi (Bay of Bengal) and Ratnakara (Indian Ocean).
Setu is the Sanskrit word to denote a bridge or causeway. It has now acquired a special significance to mean the bridge across the ocean constructed by Ram to reach Lanka.
Dhanushkodi has the only land border between India and Sri Lanka. The island was completely washed out in the cyclone of 17 December, 1964.
