Dedicated to Lord Ranganatha (a reclining form of Lord Vishnu), the Sri Ranganathaswamy Temple in Srirangam is an important shrine that receives millions of visitors and pilgrims every year. With an area of 156 acres (6,31,000 m²), the Sri Ranganathaswamy Temple is one of the largest temples in the world. In fact, the temple can be easily termed as the largest functioning Hindu temple complex in the world. The oldest structure of the temple dates back to the 10th century. There are 21 gopurams (tower), among which the Rajagopuram is the biggest temple in South India. It is 73 meters (240 feet) in height, and dates from the 17th century, although it was only completed in 1987.
