If you’re visiting Tamil Nadu's five elemental temples of Shiva, you need to see Sri Jambukeshwara, dedicated to Shiva, Parvati and the medium of water. The liquid theme is realised in the central shrine (closed to non-Hindus), whose Shiva lingam reputedly issues a nonstop trickle of water. If you’re taking bus 1, ask for ‘Tiruvanakoil’; the temple is 350m east of the main road.
