Ravana Phadi cave temple at Aihole is a great example of Chalukyan temple architecture. During the 6th century, the early Chalukyans experimented with cave temples. The Ravana Phadi cave temple is primarily is a Shiva temple.
Every Shiva temple has a Nandi positioned right opposite the Shiva linga.
There are brilliant carvings of various gods and goddesses on the interior walls of the cave temple. There is one of the Nataraja (Dancing Shiva) with Gauri and Ganesha by his side.
There is one of a rather scary meditating sage. At first it looks like a skeleton, but when you look closely you see that the representation seems of a sage who has been doing Tapasya (meditation) since ages, going by the lean skeletal figure and the strange pose he is standing in.
There is a figure of a Goddess, who looks like one of the forms of Durga.
Although the Ravana Phadi is a Shiva temple, there is a figure of the Varaha avatar of Vishnu. Chalukyas encouraged worship of both Shiva and Vishnu. Varaha appears on their royal seal as well.
There are other celestial figures as well sculpted on the walls in intricate detail.
