Vruddhamallikarjuna Swamy Temple is installed inside the Srisailam Temple premises. It is to note that Srisailam is an abode of Lord Mallikarjunaswamy. It is also one of the 12 Jyotirlinga Temples dedicated to Lord Shiva.
This lingam is said to be older than the present Mallikarjuna Swamy Lingam. There is no Nandi (Bull, vechicle of Lord) in front of it. The Lingam is uneven on its outer face which indicates the old age of Lord Shiva which was prayed by Chandravathi. Hence it is called Vrudhamallikarjuna Swamy.
Abhishekam at Srisailam Vruddha Mallikarjuna Swamy Temple is performed from 6.30 AM. Sri Vruddha Mallikarjuna Swamy Temple is a sub-temple (Upalayam) in Srisailam Temple premises.
