The Sri Ranganathaswamy Temple or Srirangam Temple is a Hindu temple dedicated to Ranganatha, a reclining form of Hindu deity, Vishnu located in Srirangam, Tiruchirapalli, Tamil Nadu, India . Constructed in the Dravidian style of architecture, this temple is glorified in the ThiviyaPirabandham, the early medieval Tamil literature canon of the Alvar saints from the 6th to 9th centuries AD and is counted among the 108 DivyaDesams dedicated to Vishnu. The temple follows Thenkalai tradition of worship. It is one of the most illustrious Vaishnava temples in South India rich in legend and history and qualifies as one of the best Tamilnadu Temples. Its location, on an island in Cauvery river, has rendered it vulnerable to natural disasters as well as the rampaging of invading armies – Muslim and European – which repeatedly commandeered the site for military encampment. The main entrance, known as the Rajagopuram (the royal temple tower), rises from the base area of around 13 cents (around 5720 sqft) and goes up to 237 feet (72 m), moving up in eleven progressively smaller tiers. The annual 21 day festival conducted during the Tamil month of Margazhi (December–January) attracts 1 million visitors. Srirangam temple is often listed as the largest functioning Hindu temple in the world, the still larger Angkor Wat being the largest existing temple. The temple occupies an area of 156 acres (631,000 m²) with a perimeter of 4,116m (10,710 feet) making it the largest temple in India and one of the largest religious complexes in the world.
SrirangaMahathmiyam is the compilation of religious accounts of the temple which detail the origins of its greatness. According to it, Lord Rama, himself an Avatar of Vishnu, worshiped the idol for a long time, and when he returned victoriously from Sri Lanka after destroying Ravana, he gave it to King Vibhishana as a token of appreciation for the latter's support for Rama against his own brother, Ravana. When Vibhishana was going via Trichy en route to Sri Lanka, the deity wanted to stay in Srirangam. Ranganatha, captivated by the devotion of a King called Dharma Varma, who was doing penance to have Lord Ranganatha to permanently stay Srirangam, stayed put, promising to cast his benign glance eternally on Lanka. Hence it is that the deity (in a reclining posture) faces South. As per another account, he was carrying it all the way to his kingdom of Sri Lanka and midway, to rest, he placed the imageon the banks of Cauvery. After performing his routine pooja, he tried to lift the Vimana, but it could not be lifted. Mahavishnu appeared to him and said that he desired to stay as Ranganatha in the place, which went on to become Srirangam. Vishnu also
desired to watch the Brahmotsavam at Tirucherai. The festivals of the temple are thus consideredsacred.Srirangam Temple is One of the Famous Temples in Tamilnadu.
