Rameswaram, an island about 160 km Southeast of Madurai is connected to the mainland both by a railway and a road bridge. It is a major pilgrim site. It is believed that the pilgrimage one undertakes in Kasi in the very north should culminate in bathing in the sacred waters of Rameswaram in order to obtain the full benefit. According to 'Ramayana', the Hindu epic, Lord Rama himself had installed the Lingam in this place which therefore gains an added importance and is held in high esteem by all the Hindus of India both Vaishnavites and Saivites. The other pilgrimage point in this island of Rameswaram is Dhanuskodi that is also called 'Sethu'. It is considered meritorious to take a dip in the sea off the coast of Dhanushkodi. There are several other small temples of interest scattered around this island.

Legends : Rama's wife Sita. In the fierce battle that ensued Ravana was defeated and killed by Lord Rama. Sita was released from Ravana's prison. Rama and Sita returned to the island of Rameswaram, which was then, called 'Gandhamadana malai' on their way back to Ayodya. The sages and 'rishis' assembled in Remeswaram to receive Rama and his consort advised him that as he had killed Ravana, a brahmin, he should atone for his sin of 'brahmahastya' by performing a purificatory rite in front of a Lingam. As there was no Lingam available, Rama asked Hanuman to obtain one from Lord Shiva himself from Mount Kailash. Hanuman went to Mount Kailash and sat in prayer to Lord Shiva requesting a Sivalingam. Days passed and Hanuman had not returned. As the auspicious time was approaching Sita moulded a Sivalingam out of sand and Rama performed his purificatory rite in front of this Lingam. Later Hanuman arrived with his Lingam given by Lord Shiva and was dejected to find that his efforts were in vain. Lord Rama seeing his dejection told him to throw away the Lingam made out of sand and to install the Lingam given to him. Hanuman then tried to lift the Sivalingam already installed but could not move it. So Rama advised him to install his Sivalingam near the one already there and requested all his followers to worship this Lingam first before worshipping the Lingam installed by himself. So this practice continues until this day as the devotees first offer prayers to this Lingam from Mount Kailash as Visvanathar before offering prayers to Lord Ramanathaswamy.

In addition to these there are other weekly and monthly 'pooja' conducted on special days based on Hindu calendar.

The temple is open from 5am to 1pm and from 3 pm to 9 pm for the devotees and 'pooja' is performed six times on a normal day. There are additional 'pooja' on special days. In addition it is possible to arrange special 'pooja' on behalf of the devotees by paying the appropriate fees at the 'Devasthanam' office.
