Why is Pamban Island or Rameswaram Island a prominent one in India?

Pamban Island, also known as Rameswaram Island, is an island located between India and Sri Lanka. The island is famous for Rameswaram, which is a pilgrimage destination.

 Pamban Island is comparatively big in size. It extends from the township of Pamban to the remains of Dhanushkodi. Rameswaram is the largest and most populous town on the island. It is one of the most sacred religious sites.

 At the eastern tip of the island lies the site of Dhanushkodi, a harbour and a pilgrimage centre, which was washed away by the December 1964 cyclone. Prior to its destruction, it was a flourishing township and a prominent place of pilgrimage.
