One of the most famous Jyotirlinga Temple Rameswar is situated in the state of Tamilnadu. The sanctification of the temple of Lord Rameshwar was done by Lord Rama himself, and thus this name. It is situated in a large island surrounded by sea. It is approached from Madurai, which by itslf is well connected by all means of transportation.
The legend is that Lord Rama started meditation of Lord Shiva for getting his blessings to get the victory over 'Lanka' and to defeat Ravana for rescuing his beloved wife Sita. Lord Shiva Blessed Lord Rama and conferred his eternal light i.e. Jyoti, which was the origin of the Rameswar Jyotir Lingam.
