Myths / Legends
One of the Legends is of Princess Chandravathy of the Chandragupta pattinam Kingdom who visited the Srisailam hills and found a cow shedding milk on a lingam. She immediately offered prayers offering mallika flowers (jasmine) and hence the Lord is Mallikarjuna - Mallika archita Swamy
The temple has been historically around since 2nd Century AD and was rebuilt by the King Harihara Raya of the Vijayanagara Empire around 1404 AD.
