Bhavani Arulmigu Sangameshwarar Temple (historically known as Thiru Nana / Kooduthurai) is an ancient and world-famous Paadal Petra Sthalam in the Kongu Naadu region of Tamil Nadu. Perched dramatically at the holy confluence (Kooduthurai) where the sacred Cauvery River, Bhavani River, and the invisible subterranean Amudha River unite, Bhavani is celebrated across India as the Triveni Sangam of South India.
Enshrined in the 7th-century Tamil Tevaram hymns composed by child-saint Thirugnanasambandar, the temple is unique for housing both Lord Shiva (Sangameshwarar) and Lord Vishnu (Aadhikesava Perumal) within the same temple sanctuary, symbolizing Hari-Hara unity. The 10-acre temple complex features a grand 5-tiered Rajagopuram, an inner sanctum housing the Swayambhu Lingam of Sangameshwarar, a dedicated shrine for Goddess Vedanayaki, the ancient Ilanthai tree (Sthala Vriksham), and the historic Collector William Garrow Ivory Cradle. Millions of pilgrims visit Bhavani to perform holy river immersion (Sangam Snanam) and ancestral rituals (Pithru Tarpanam).
