When was Sri Rama Sethu built and by whom?

Answer 1

The temple of Sri Ramanatha, which has over the centuries grown into its present gigantic dimensions, stands on the eastern shore of an island, which is shaped like a conch, which Lord Vishnu bears in one of His hands. No field is ploughed or oil presses any where in the island. A magnificent railway bridge, over a kilometre long and constructed at the beginning of the twentieth century, connects it with the mainland.
To help the pilgrims walking incredible distances, philanthropists used to construct rest houses at intervals along the way. The last of them before Rameshwaram was Thangachimadam, a few kilometres away on the island. Modern means of transport have made these rest houses superfluous. But in their time they were most useful, even vital. The Sethupathis of Ramanathapuram, of which the district Rameshwaram is an administrative part, were called the "guardians of the Sethu", the bridge which, according to tradition, was built for Sri Rama to cross over into Sri Lanka when He set out to recover Sita.


Sethu
5-km south of the temple is Sethu, where there is a celebrated temple of Sri Anjaneya, and where, tradition holds, Sri Rama built a bridge to Sri Lanka. In Devipatnam, or Navapashanam, also by the sea, there are nine stones visible at low tide. It is believed that they were set up by Sri Rama to represent the nine planets, the Navagrahas.

Answer 2

Sri Rama Sethu

Answer 3

Rama's sethu was built by Rama with the held of Sugreeva's army, during Ramayana period. This is what wikipedia has to say about its history.

The name Rama's Bridge originate in Hindu belief. According to the Hindu epic Ramayana (Chapter 66, The Great Causeway, the bridge was constructed at Rama's request by his allies. The bridge was supported on floating sand rocks but the gods were said to have later anchored the rocks to the sea bed, thus creating the present chain of rocky shoals. It was said to have helped Rama to reach Sri Lanka to rescue his wife Sita from the demon king (Asura) called Ravana, who was then the ruler of Lanka.

Some Hindu groups claim that the bridge is evidence that events narrated in the Ramayana epic actually took place and cite NASA's imagery of it as proof of their claims. NASA has distanced itself from such claims:

"The images [...] may be ours, but their interpretation is certainly not ours. [...] Remote sensing images or photographs from orbit cannot provide direct information about the origin or age of a chain of islands, and certainly cannot determine whether humans were involved in producing any of the patterns seen."

Archaeology
Archaeological studies of the bridge are ongoing, and some archaeologists claim to have found evidence suggesting that the bridge may be older than expected.

Sea levels rose about 10 or 20 metres in the 6th millennium BCE to reach levels similar to today, so in 6000 BCE the bridge would have been an isthmus situated above sea level. As such, it almost certainly would have been a viable route for humans to have reached Sri Lanka by dry land..

Answer 4

I think you are referring to Adam's Bridge near Rameshwaram. In Ramayana, mythologically, the bridge was built by the Vanaras to help Rama and Lakshmana go to Lanka to save Sita. Geographically, they are just land masses, mostly from the runoff of lava from the eastern ghats.

Answer 5

ancient bridge (it's been sink) they said that it's 17,30,000 years
old. And that was build by SRI RAMS waner sena.
