This is one of the almost completed monuments attributed to the time of Narasimha Pallava. This cave mandapam and the Adi Varaha mandapam which is currently under worship sport similar wall panels. There are four wonderful relief panels Ė Varaha holding aloft Boodevi, Gajalakshmi, Durga and Trivikrama.
There is a small tank dug at the entrance of the mandapam. There are two pillars & 2 pilasters with sitting lion as the base. On the roof there is a level of kudus with lotus carvings and above that are the salas (mini shrines).
On either side of the empty garbagriham
are two dwarapalakas in three fourth profile, their outer arm on their
hip and the inner arm pointing to the garbagriham. As a rare feature,
there are two more dwarapalakas on the side projecting wall, at right angle,
facing the Varaha & Trivikrama panels.
On the left side are the Varaha panel on the side wall and the Gajalakshmi panel on the facing wall. On the right side are the Trivikrama panel on the side wall and the Durga panel on the facing wall.
On the wall opposite the Varaha panel is the scene depicting Trivikrama (ulagalanda Perumal), Vishnu raising his left leg to reach to the sky. In his Vamana avatara, the Lord as Vamana, a Brahmin dwarf subdues the asura Mahabali. (Vamana asks for three steps of land. As the amused Mahabali watches, he covers the entire earth with one foot, the heavens with his second step and places his foot on Mahabaliís head for the third step.) In this panel, he is seen measuring the heavens as Trivikrama. He has eight arms. His main right arm is raised to the roof and he holds weapons in his other arms. There are figures around Vishnu in three levels. At ground level are four men, two on either side, seated to indicate the earth. The first figure on the left seen in a sprawling posture could be Mahabali. At the second level are the sun & moon identified by the halo around the head, indicating the sky. There are heavenly beings, Brahma on the right and Siva on the left in the 3rd level, seated on lotus, i.e, Lord Vishnu has reached even above the skies to measure his second step. Beside Brahma is an animal headed form, beating a drum in jubilation. Just below Brahma in the second level is seen a figure falling down to earth.
