Rameswaram a small island in the Gulf of Mannar, is a major pilgrim centre.It is connected to the mainland by road and rail bridges. Rameswaram is holy, because Sri Rama, on his return from SriLanka, offered his thanks to Lord Siva here. Every Hindu Devout hopes to visit Rameswaram at least once in his Lifetime. This place is thus equally sacred to both Vaishnavites and Saivites. The Ramanathaswamy temple is renowned for its magnificent corridors and massive sculptured pillars. Its corridors are the longest in India.
