[4] The effort expended often astonishes visitors, but seen from one aspect, a rock-cut structure is a decorated rock quarry; most of the stone removed was typically put to economic use elsewhere.
The sanctuary in all Indian religious structures, even free-standing ones, was designed to have the same cave-like feeling, as it is generally small and dark, without natural light.
Other early cave temples are found in the western Deccan; these are mostly Buddhist shrines and monasteries, dating between 100 BC and 170 AD.
Historically, artisans carried forward design elements from wood in their rock-cut temples: skilled craftsmen carved rock to imitate timber texture, grain, and structure.
Some of the more sumptuous cave temples, commissioned by wealthy traders, included pillars, arches, and elaborate facades.
Although cave temples continued to be built until the 12th century, rock-cut architecture became almost totally structural in nature.
[9] The Rock Shelters of Bhimbetka, now designated as a UNESCO World Heritage Site, are located on the edge of the Deccan Plateau, where dramatic erosion has left massive sandstone outcrops.
[22] These artificial caves exhibit an amazing level of technical proficiency, the extremely hard granite rock being cut in geometrical fashion and polished to a mirror-like finish.
The caves are situated on two adjacent hills, Udayagiri and Khandagiri, mentioned as Kumari Parvat in the Hathigumpha inscription.
[20] When Buddhist missionaries arrived, they naturally gravitated to caves for use as temples and abodes, in accord with their religious ideas of asceticism and the monastic life.
The Western Ghats topography, with its flat-topped basalt hills, deep ravines, and sharp cliffs, was suited to their cultural inclinations.
The earliest of the Kanheri Caves were excavated in the 1st and 2nd centuries B.C., as were those at Ajanta, which were occupied continuously by Buddhist monks from 200 BCE to 650 AD.
[30] Facades were added to the exteriors while the interiors became designated for specific uses, such as monasteries (viharas) and worship halls (chaityas).
Over the centuries, simple caves began to resemble free-standing buildings, needing to be formally designed and requiring highly skilled artisans and craftsmen to complete.
These artisans had not forgotten their timber roots and imitated the nuances of a wooden structure and the wood grain in working with stone.
[31] Early examples of rock-cut architecture are the Buddhist and Jain cave basadi, temples and monasteries, many with gavakshas (chandrashalas).
[31] 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.
The construction of caves would wane after the 2nd century CE, possibly due to the rise of Mahayana Buddhism and the associated intense architectural and artistic production in Gandhara and Amaravati.
[20] The building of rock-cut caves would revive briefly in the 6th century CE, with the magnificent achievements of Ajanta and Ellora, before finally subsiding as Hinduism replaced Buddhism in the sub-continent, and stand-alone temples became more prevalent.
[33] Skilled artisans crafted living rock to imitate timbered wood (such as lintels) in construction and grain and intricate decorative carving, although such architectural elements were ornamental and not functional in the classical sense.
Pancha Rathas is an example of monolith Indian rock cut architecture dating from the late 7th century located at Mamallapuram, a UNESCO World Heritage Site.
The Kailash Temple was created through a single, huge top-down excavation 100 feet deep down into the volcanic basaltic cliff rock.
They have a history of around 4,000 years in India, first appearing in the Bronze Age Indus Valley civilization, reappearing around the 5th century CE, and then constructed until relatively recent times, with some still in use.
[45] Famous examples include: Chand Baori, Rani ki vav, Step-well of Ambapur, and the Dada Harir Stepwell.
