Ucchipillaiyar Temple

The largest functioning Hindu temple complex in the world, spanning around 156 acres across seven concentric enclosures and 21 gopurams, and foremost among the 108 Divya Desams of Lord Vishnu. Lord Ranganatha is worshipped here in his reclining form, and the temple's Vaikunta Ekadasi festival draws vast crowds each year.

The 'Apas' (water) Pancha Bhoota Sthalam, where a natural spring in the sanctum keeps the Shiva lingam partially submerged despite being underground. Located near Srirangam and dedicated to Shiva as Jambukeswarar and his consort Akhilandeswari, it is one of the few shrines where the goddess holds greater prominence than the god.

One of Tamil Nadu's most visited temples, dedicated to Goddess Mariamman and located 13 km from Trichy on the Trichy–Srirangam pilgrimage circuit. It draws over a million pilgrims a year, many seeking the goddess's protection from disease and the fulfilment of personal vows.

A UNESCO World Heritage Chola-era temple built by Raja Raja Chola I and completed around 1010 CE, crowned by a 66-metre vimana capped with a single granite block weighing an estimated 80 tonnes. Dedicated to Lord Shiva, it remains a masterpiece of Dravidian architecture and Chola engineering.
