Rameshwaram Temple is located in the Ramanathapuram district of the state of Tamil Nadu. This temple is regarded one of the Char Dhams and is a sacred Hindu shrine. Ramanatha Swamy Temple is another name for Rameshwaram Temple. One of the twelve Jyotirlingas, the Shivling installed at this temple, is thought to be one of them. In the same manner that Kashi is significant in North India, Rameshwaram is significant in South India. Rameshwaram is a conch-shaped island surrounded by the Indian Ocean and the Bay of Bengal. This island was once connected to India's mainland, but it was progressively cut off by the ocean's high waves, resulting in the island being encircled on all sides by water.

History
While returning from Sri Lanka, Lord Shri Ram is said to have worshipped Lord Shiva here. He is commemorated by the Rameshwar Temple and Rameshwar Island. Lord Rama and his wife Goddess Sita are said to have returned to India only after stepping on the banks of Rameshwaram after killing Ravana. Lord Rama desired to worship Shiva in order to absolve himself of the guilt of murdering a Brahmin. Because the island lacked a temple, Shri Hanuman was dispatched to Mount Kailash to get Lord Shiva's idol. When Hanuman failed to reach the Shivling in time, Goddess Sita created a Shivling by tying sea sand in his fist, which Lord Rama worshipped. Later, Hanuman's Shivling was put there as well.
In the 15th century, King Udaiyan Sethupati and Vaishya residents of Nagoor constructed a 78-foot-high gopuram. Tirumalaya Sethupathi built the second wall of the south side of the temple in the sixteenth century. At the temple's entryway, Tirumalay's and his son's idols are seated. King Udaiyan Sethupathi Kattatswara, a servant of King Vishwanatha Nayaka of Madurai, constructed the Nandi Mandap in the sixteenth century. The present-day Rameshwaram temple is thought to have been built in the seventeenth century. The construction of this temple was ordered by King Kizhavan Sethupati or Raghunath Kilavan, according to analysts. The Sethupati Kingdom's Jaffna Raja made a considerable contribution to the temple's building.
