Temple is one of the most ancient temples, believed to exist before 2nd century A.D. The fact that Siva and Parvathi are placed on a single "peetam" makes the temple different from many other ancient temples like Srisailam and Srikalahasti.
It is one of the ancient temples, believed to exist before 2nd century AD. According to the temple history, the Peetam was placed by Agasthya Maharshi. According to the Archeology Survey of India, this Jaladheeswara Temple is the fourth ancient temple in Andhra Pradesh, which was supposed to have existed long back before 2nd century. This Siva Lingam has similar features as that of existing in ancient temples like Gudimallem, Amaravati, and Draksharamam. The presiding deity derived His name Jaladheeshwara, as He was worshipped by fishermen, sailors, and merchants venturing out on journeys by ship centuries ago. Here you find Lord Shiva in the form of a Shivalinga and His consort Parvathi Devi on the same pedestal which is a very rare sight. As usual, Nandeeshwara is seen before the doors of the sanctum sanctorum. But here in this temple, Nandi is seen at Shiva and Parvathi Devi by sideway glances.
The Temple has many more beautiful Idols of Lord Ugra Narasimha, Lord Kalabhairava who are seen as Dwarapalakas, and Saraswati Matha and others. The Idol of Saraswathi resembles Mohenjadara image and is unique in many respects. It houses all the worshipful deities inappropriate shrines.
