New Delhi: Ram Sethu, also known as Sethusamudram and Adam's Bridge is a stretch of limestone shoals that runs from Pamban Island near Rameshwaram in South India to Mannar Island off the northern coast of Sri Lanka.
It formed part of a land bridge that joined Sri Lanka to the continent of Asia during the last ice age.
Hindu believers hold it as the structure that Lord Rama and his army of apes and monkeys built to reach demon king Ravana's Lanka.
