The Sri Ranganathaswamy Temple in Srirangam is a famous Hindu temple dedicated to Lord Ranganatha, a reclining form of Lord Vishnu. It is the first and foremost among the 108 Divya Desams, the holy abodes of Lord Vishnu. Boasting of a real specimen of superb architecture, the temple occupies an area of 156 acres that makes it the largest temple in India. Srirangam temple can be easily termed as the biggest functioning Hindu temple in the world (it's termed as biggest "functioning" because Angkor Wat is the biggest but non-functioning Hindu temple in the world). The temple is enclosed by 7 concentric walls and the total length of these seven walls is 32,592 feet or over six miles. Moreover it houses 21 gopurams in which are 236 feet high with 13 Nilays and 12 Kalasamswhich are kept on the top of the Gopurams. It took almost 7 years to complete theseGopuram. The annual chariot festival of Tamil Nadu held at Sri Ranganathaswamy temple attracts hordes of tourist to Tiruchirapalli.
