This cave temple dedicated to Vishnu is a Muttaraiyar excavation as attested by an inscription recording the renovation of the temple and an endowment by Perumbidugu Perumdevi, mother of Sattan Maran also called Videlvidugu Viluperadiaraiyan, a contemporary and vassal of Pallava king Nandivarman II Pallavamalla (AD 731-796). Nevertheless, the temple is slightly older and dated to closing decades of seventh century.

The temple consists of an ardha-mandapa in front of a rectangular sanctum. In the sanctum there is beautiful and vibrant depictions of Anantasayi Vishnu recumbent on the serpent Adisesha with Lakshmi seated on his breast. He is being shown surrounded by other deities like Garuda, Chitragupta, Markandeya, Brahma, the Devas, the Vasus, and the Kinnaras. There are two demons near the feet of the gods and sheltered there is Bhudevi.

Tirumangai Alvar, a Vaishnava saint of 8th cenutury AD had sung about this deity. There are number of other structures in the complex of later periods.

Some of the bronzes, now preserved in the temple, dates back to 8th-9th century AD.
