Mahendravadi is located in Arakonam Taluk, Vellore District of Tamil Nadu, India. The cave temple in this village is an important one as it is the only cave temple dedicated to Lord Vishnu which was constructed by Mahendravarman I (600-630 CE). This cave is excavated on a free standing boulder. The front facade of the east facing cave temple is supported on two pillars and two pilasters. The pillars are cubical on top and bottom with an octagonal intermediate portion. This cave shrine has two rows of pillars and pilasters.

The shrine is carved at the back wall of the cave. The entrance of the shrine has two Dwarapalaks as bas-relief images. The postures of these Dwarapalaks appear as if they are in motion and they are facing away from each other.

The idol of Yoga Narasimha is placed inside the shrine; it is obviously a later addition. The original idol or stucco image is missing.
