Their temple building activity can be categorised into three phases. The early phase began in the last quarter of the 6th century and resulted in many cave temples, prominent among which are three elementary cave temples at Aihole (one Vedic, one Jain and one Buddhist which is incomplete), followed by four developed cave temples at Badami (of which cave 3, a Vaishnava temple, is dated accurately to 578 CE). These cave temples at Badami are similar, in that, each has a plain exterior but an exceptionally well finished interior consisting of a pillared verandah, a columned hall (mantapa) and a cella (shrine, cut deep into rock) which contains the deity of worship. In Badami, three caves temples are Vedic and one in Jain. The Vedic temples contain large well sculpted images of Harihara, Mahishasuramardhini, Varaha, Narasimha, Trivikrama, Vishnu seated on Anantha (the snake) and Nataraja (dancing Shiva).
