This temple is located right inside Kanchipuram and is one of the sacred Shiva temples in the town. There is a much more ancient Parasareshwarar Shiva linga inside the temple but this has become very famous.
Vazhaku in Tamil means Court case or a legal dispute. Vazhakarutheeswarar means "the Lord who demolised cases". Even though its small temple, pilgrims visit it in large numbers on Mondays/Thurdays. Various kinds of lamps are lit - some with Ghee, some with Oil, some with different kind of wigs made of lotus stem etc with prayers to the lord to resolve their legal problems.
