Early examples of rock-cut architecture are the Buddhist and Jain cave basadi, temples and monasteries, many with gavakshas ("chandrashalas"). The ascetic nature of these religions inclined their followers to live in natural caves and grottos in the hillsides, away from the cities, and these became enhanced and embellished over time. Although many temples, monasteries, and stupas had been destroyed, by contrast, cave temples are very well preserved as they are both less visible and therefore less vulnerable to vandalism as well as made of more durable material than wood and masonry. There are around 1200 cave temples still in existence, most of which are Buddhist. The residences of monks were called Viharas and the cave shrines, called Chaityas, were for congregational worship. The earliest rock-cut "garbhagriha", similar to free-standing ones later, had an inner circular chamber with pillars to create a circumambulatory path (pradakshina) around the stupa and an outer rectangular hall for the congregation of the devotees.
