Shri Ram Setu : The bridge built by the Vanar Sena to reach the shores of Lanka.
Those who say that Lord Ram was a fiction, this mighty Ram Setu is a tight slap on their face. It is there since Shri Ram's time. Trying to destroy this is a failed attempt to deny the existence of Lord Ram. People may close their eyes but truth will never change.
We all owe a responsibility to protect our heritage, to protect our Dharma. We will protect Ram Setu. Chiranjeev Shri Hanuman is with us.
The bridge is 18 miles (30 km) long and separates the Gulf of Mannar (southwest) from the Palk Strait (northeast). Some of the sandbanks are dry and the sea in the area is very shallow, being only 3 ft to 30 ft (1 m to 10 m) deep in places, which hinders navigation. It was reportedly passable on foot up to the 15th century until storms deepened the channel: temple records seem to say that Rama’s Bridge was completely above sea level until it broke in a cyclone in AD 1480.
Early surveys and dredging efforts
Owing to shallow waters, Adam's bridge presents a formidable hindrance to navigation through the Palk strait. Though trade across the India-Sri Lanka divide has been active since at least the first millennium BC, it has been limited to small boats and dinghies. Larger ocean-going vessels from the West have had to navigate around Sri Lanka to reach India's eastern coast. Eminent British geographer Major James Rennell, who surveyed the region as a young officer in the late 18th century, suggested that a "navigable passage could be maintained by dredging the strait of Ramisseram [sic]". However little notice was given to his proposal, perhaps because it came from "so young and unknown an officer", and the idea was only revived 60 years later.
In 1823, Sir Arthur Cotton (then an Ensign), was trusted with the responsibility of surveying the Pamban channel, which separates the Indian mainland from the island of Rameswaram and forms the first link of Ram Setu. Geological evidence indicates that this was at one point bridged by a land connection, and some temple records suggest that the connection was broken by violent storms in 1480. Cotton suggested that the channel be dredgedto enable passage of ships, but nothing was done until 1828, when some rocks were blasted and removed under the direction of Major Sim.
A more detailed marine survey of Ram Setu was undertaken in 1837 by Lieutenants F. T. Powell, Ethersey, Grieve and Christopher along with draughtsman Felix Jones, and operations to dredge the channel were recommenced the next year. However these, and subsequent efforts in the 19th century, did not succeed in keeping the passage navigable for any vessels except those with a light draft.
