The temple is one of the 108 Purana Kshethrams of Vaishnavate tradition. The temple is constructed in the Dravidian style of architecture and rock-cut architecture, the temple is located in the Salem–Namakkal–Trichy Road. Based on the architectural features, historians believe that the temple was built during the 6th century by the Adiyamans also called Satyaputras as evident from the inscription mentioning the temple as 'Adiyendra Vishnu Gruham' or 'The house of Vishnu of the Adiyaman kings'. This temple plays an important role in history as it has four main Sanskrit inscriptions dated around 6th century to 8th century CE, and is also used to date another cave temple excavated in the same hill, as that cave temple as no Inscriptions.
