Chathapurinathar temple is dedicated to the worship of Lord Shiva, as is the case with most temples in and around Chidambaram. Since Shiva is worshipped here as Lord Chathapurinathar, the temple is frequented by devotees of Lord Shiva around the year. By his side, the other deity being worshipped here is Osai Kodutha Nayagi. The name comes from a story where the goddess animated a pair of pure gold cymbals that the lord gifted to a devotee, which could not make sound till then.
The temple is a place where you come not only to worship the deities but also hoping for miracle cures. For the deity is known to have cured what many, including modern science, consider to be incurable diseases. The temple is but only a kilometer away from Chidambaram and is located at a place called Tirukolakka.
