Marundeeswarar Temple or Oushadheeshwar Temple is a Hindu temple dedicated to the deity Shiva. Shiva is worshipped as Marundeeswarar, and is represented by the lingam. His consort Sati is depicted as Anjanakshi. The presiding deity is associated with the 7th century Tamil Saiva Nayanars Sundarar. The temple is counted as a twin temple along with Kachabeswarar temple, the place where Lord Vishnu did penances to Lord Shiva to incarnate into his Kachaba (Tortoise) Avatar.
