Udayagiri caves contain iconography of Vaishnavism (Vishnu), Shaktism (Durga and Matrikas) and Shaivism (Shiva). They are notable for the ancient monumental relief sculpture of Vishnu in his incarnation as the man-boar Varaha, rescuing the earth symbolically represented by Bhudevi clinging to the boar's tusk as described in Hindu mythology. The site has important inscriptions of the Gupta dynasty belonging to the reigns of Chandragupta II (c. 375-415) and Kumaragupta I (c. 415-55). In addition to these, Udayagiri has a series of rock-shelters and petroglyphs, ruined buildings, inscriptions, water systems, fortifications and habitation mounds, all of which remain a subject of continuing archaeological studies. The Udayagiri Caves complex consists of twenty caves, of which one is dedicated to Jainism and all others to Hinduism. The Jain cave is notable for one of the oldest known Jaina inscriptions from 425 CE, while the Hindu caves feature inscriptions from 401 CE.
