The Sri Ranganathaswamy Temple or Thiruvarangam is a Hindu temple glorified by Alvars in their Divya Prabhanda and is one 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. The temple has played an important role in Vaishnavism history starting with the 11th-century career of Ramanuja and his predecessors Nathamuni and Yamunacharya in Srirangam.
The temple occupies an area of 155 acres with 81 shrines, 21 towers, 39 pavilions and many water tanks integrated into the complex making it the world’s largest functioning Hindu temple.
The Srirangam temple is the largest temple compound in India and one of the largest religious complexes in the world. Some of these structures have been renovated, expanded and rebuilt over the centuries as a living temple. The latest addition is the outer tower that is 67 metres (220 ft) tall, completed in 1987.
The temple town is a significant archaeological and epigraphical site, providing a historic window into the early and mid medieval South Indian society and culture.
