Dhanushkodi is only about ten kilometres long, yet its significance in Indian mythology is considerably beyond its size. It is reported that Rama built his bridge to cross into Lanka here. Dhanushkodi is only about 30 kilometres from Sri Lanka. Satellite pictures and geographical studies suggest that a multitude of sandbanks, reefs, and shoals extend from that point all the way to the Sri Lankan island of Mannar. This geographical landmark is known as Adam's Bridge (or Rama's Bridge throughout most of India).
