Built in the 17th century, the Ramanathaswamy Temple is the major highlight of Rameshwaram and is an important religious shrine to be visited in the entire South India. Dedicated to Lord Shiva, the temple holds mythological significance as it is said to be built by Lord Rama itself. Located near the sea shore, this magnificent temple is renowned for its 1200 massive granite columns and corridors. The world’s longest corridor is also situated here which is 197 meters long and 133 meters broad. The temple also showcases a real specimen of Dravidian architecture and is noteworthy for its 38.4 meters tall Gopuram. One of the noticeable features of the temple is 22 theertha kundams or water wells where all the devotees should take bath before having darshan of the deity.
