Thirunavalur Arulmigu Bhaktajaneswarar Temple (historically known as Thiru Naval) is an ancient 10th-century Chola granite sanctuary and the 8th holy Paadal Petra Sthalam in the historic Nadu Naadu region of Tamil Nadu. Located along the Chennai–Tiruchirappalli national highway (NH45) in Kallakurichi district, this revered temple holds supreme spiritual importance as the sacred birthplace of Saint Sundaramurthy Nayanar, one of the celebrated Shaivite Holy Trio (Muvavar).
Enshrined in the 7th-century Tamil Tevaram hymns composed by Saint Sundarar, the temple derives its name from the holy Naval tree (Jambool / Syzygium cumini) under which Sukra Bhagavan (Venus) performed penance. Constructed in granite by Chola Crown Prince Rajaditya (son of Parantaka Chola I) before the fateful Battle of Takkolam (949 CE), the temple complex features a majestic three-tiered Rajagopuram, an inner sanctum housing the Swayambhu Lingam of Bhaktajaneswarar, a dedicated shrine for Goddess Sundarambigai, a special birth shrine for Saint Sundarar, and the sacred Garuda Theertham. Devotees visit Thirunavalur to pray for Sukra Dosha relief, musical and poetic wisdom, and ancestral blessings.
