Srirangam  March 20, 2014: It is a Hindu temple dedicated to Ranganatha, a reclining form ofHindu deity, Vishnu located in Srirangam, Tiruchirapalli, Tamil Nadu, India . Constructed in the Dravidian style of architecture, this temple is glorified in the Thiviya Pirabandham, the early medieval Tamil literature canon of the Alvar saints from the 6th–9th centuries AD and is counted as the first and foremost among the 108 Divya Desams dedicated to Vishnu.

It is one of the most illustrious Vaishnava temples in South India rich in legend and history. 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 sq ft) 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.

The vimanam (shrine over the sanctum sanctorum), the Ranga vimana is shaped like omkara (om symbol) and is plated with gold. Sri Ranganthar reclines on Adisesha, the coiled serpent. Images of Vibhishana,Brahma, Hanuman, Garuda, the symbols of Vishnu – conch and discuss are seen inside the sanctum. Ranganayaki shrine is in the second precint of the temple. The common reference to the goddess is padi thaanda pathni, meaning lady who doesn't cross the boundaries of ethics. Literally, the festival deity of Ranganayaki also does not come out of the shrine and it is Ranganthar who visits Ranganayaki. There are three images of Ranganayaki within the sanctum.

The complex houses shrines of dozens of forms of Vishnu including Chakkarathazhwar, Narasimha, Rama, Hayagreeva and Gopala Krishna. There are separate shrines for Ranganayaki and the major saints in the Vaishnava tradition, including Ramanuja. The Venugopala shrine in the south-west corner of the fourth enclosure of the temple is the work of Chokkanatha Nayak. An inscription of 1674 specifies this Nayak king as the patron. The exterior of the vimana and attached mandap (hall) have finely worked pilasters with fluted shafts, double capitals and pendant lotus brackets. Sculptures are placed in the niches of three sides of the sanctuary walls; maidens enhance the walls in between. The elevation is punctuated with secondary set of pilasters that support shallow eaves at different levels to cap larger and smaller recesses. The sanctuary is crowned in the traditional fashion with a hemispherical roof. The double-curved eaves of the entrance porch on the east side are concealed in a later columned hall.Dhanvantari, a great physician of ancient India is considered to be an incarnation of Vishnu – there is a separate shrine of Dhanvantari within the temple.
