, or the Holy Koneswaram Temple, is a Hindu temple in Thirukonamalai (Trincomalee) on the east coast of Sri Lanka. The temple lies on a high rocky promontory surrounded on three sides by the sea. It bears a history of over three millennia with its records indicating its roots in 1580 BC. This, still beautiful, historical monument is what remains of what once was a sprawling temple city equal to the ancient city of Madurai, India.
