Vaitheeswaran Koil, Hindu temple in Sirkali, India

Vaitheeswaran Koil is a Hindu temple in Sirkali, India, known for its connection to traditional healing practices. Stone pillared halls lead to an inner shrine where a statue of Shiva as healer deity receives worship.

The shrine emerged during the Chola dynasty as a pilgrimage site for the sick and those seeking cures. Royal inscriptions mention donations to maintain medical care and religious rituals at this location.

The name Vaitheeswaran derives from the Tamil vaidya (doctor) and Ishvara (god), and the village is also called Pullirukavelur after Jatayu, the Rig Veda, Muruga's vel and Surya, who are said to have worshipped here. Devotees dissolve jaggery in the Siddhamirtham tank, a practice believed to cure skin diseases, and children receive their first tonsure at the temple.

The temple lies on the Sirkazhi–Mayiladuthurai state highway, 13 km from Mayiladuthurai and 27 km from Chidambaram, with frequent Tamil Nadu government buses and a railway station on the Chennai–Mayiladuthurai line. Devotees bathe in the Siddhamirtham tank before entering the sanctum, and the southern gateway from the second precinct leads straight to the tank, facing the Thaiyalnayaki shrine. The five-tiered gopuram and two inner gopurams mark the entrance; the neem tree, the sthala vriksha, stands near the eastern gateway.

In the courtyard, devotees queue to break coconuts on designated stones before approaching the deity. A separate shrine houses palm leaf manuscripts used during astrological consultations.
