Buddhist caves in India are an important part of Indian rock-cut architecture. These caves are more various and found in greater abundance than any other form of rock-cut architecture around the world. Buddhist caves were created by carving them out of solid natural rock. Rock that is not part of the structure is removed until the only rock left is the architectural elements of the excavated interior.

Many of these caves contain works of art of global importance, and most are adorned with exquisite stone carvings. These ancient and medieval structures represent significant achievements of structural engineering and craftsmanship.

In India, caves have long been regarded as places of sanctity. Caves that were enlarged or entirely man-made were felt to hold the same sanctity as natural caves. In fact, the sanctuary in all Indian religious structures, even free-standing ones, retains the same cave-like feeling of sacredness, being small and dark without natural light. The oldest rock-cut architecture is found in the Barabar caves, Bihar built around the 3rd century BC. Other early cave temples are found in the western Deccan, mostly Buddhist shrines and monasteries, dating  between 100 BC and 170 AD. Originally, they were probably accompanied by wooden structures, which would have deteriorated over time. Historically, rock-cut temples have retained a wood-like theme in adornment; skilled craftsmen learned to mimic timber texture, grain, and structure. The earliest cave temples include the Bhaja Caves, the Karla Caves, the Bedse Caves, the Kanheri Caves, and some of the Ajanta Caves. Relics found in these caves suggest a connection between the religious and the commercial, as Buddhist missionaries often accompanied traders on the busy international trading routes through India. Some of the more sumptuous cave temples, commissioned by wealthy traders, included pillars, arches, and elaborate facades during the time maritime trade boomed between the Roman Empire and south-east Asia.

Although free standing structural temples were being built by the 5th century, rock-cut cave temples continued to be built in parallel. Later rock-cut cave architecture became more sophisticated as in the Ellora Caves, culminating ultimately in the monolithic Kailash Temple. Although cave temples continued to be built until the 12th century, rock-cut architecture became almost totally structural in nature, made from rocks cut into bricks and built as free standing constructions. Kailash was the last spectacular rock-cut excavated temple. There are also a number of rock reliefs, relief sculptures carved into rock faces, outside caves or at other sites.

Early natural caves
The earliest caves employed by humans were natural caves used by local inhabitants for a variety of purposes, such as shrines and shelters. Evidence suggests that the caves were first occupied and slightly altered during the Palaeolithic and Mesolithic periods, up to about 6000 BC, though the changes do not really amount to architecture. Early examples included overhanging rock decorated with rock-cut designs. The Rock Shelters of Bhimbetka, a World Heritage Site, are located on the edge of the Deccan Plateau, where dramatic erosion has left massive sandstone outcrops. The area's many caves and grottos have yielded primitive tools and decorative rock paintings.

During the time of the Buddha (c. 563/480 or c. 483/400 BCE), Buddhist monks were also in the habit of using natural caves, such as the Saptaparni Cave, southwest from Rajgir, Bihar. Many believe it to be the site in which Buddha spent some time before his death, and where the first Buddhist council was held after the Buddha died (paranirvana). The Buddha himself had also used the Indrasala Cave for meditation, starting a tradition of using caves, natural or man-made, as religious retreats, that would last for over a millennium.

Artificial caves of Eastern India (3rd-2nd centuries BCE)
In the 3rd century BCE Indian rock-cut architecture began to develop, starting with the already highly sophisticated and state-sponsored Barabar caves in Bihar, personally dedicated by Ashoka circa 250 BCE. 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.

These caves were initially dedicated to the Ajivikas, but the last two caves dedicated by Ashoka may have been affiliated with Buddhism.

Artificial caves of Western India
After the Barabar Caves, huge efforts were made at building religious caves in Western India until the 6th century CE. However, the polishing of cave walls was abandonned, never to be revived. Such grandiose caves as Karla Caves (1st century CE) or the Ajanta Caves (5th century CE) do not have any polishing either. This may be due to the fact that Mauryan caves where dedicated and sponsored by the Mauryan Imperial government, allowing for huge ressources and efforts to be spent, whereas later caves where essentially the result of donations by commoners, who could not afford as high a level of spending.

First wave of construction (2nd century BCE-)
Probably owing to the 2nd century BCE fall of the Mauryan Empire and the subsequent persecutions of Buddhism under Pushyamitra Sunga, it is thought that many Buddhists relocated to the Deccan under the protection of the Andhra dynasty, thus shifting the cave-building effort to western India: an enormous effort at creating religious caves (usually Buddhist or Jain) continued there until the 2nd century CE, culminating with the Karla caves or the Pandavleni caves. These caves generally followed an apsidal plan with a stupa in the back fot the chaityas, and a rectangular plan with surrounding cells for the viharas.

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. As the Buddhist ideology encouraged involvement in trade, monasteries often became stopovers for inland traders and provided lodging houses along trade routes. As mercantile and royal endowments grew, cave interiors became more elaborate, with interior walls decorated in paintings, reliefs, and intricate carvings. Numerous donors provided the funds for the building of these caves and left donatory inscriptions, including laity, members of the clergy, government officials, and even foreigners such as Yavanas (Greeks) representing about 8% of all inscriptions. 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.

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.

Second wave of cave construction (5th-6th century CE)
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. 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.

The Ajanta Caves in Maharashtra, a World Heritage Site, are 30 rock-cut cave Buddhist temples carved into the sheer vertical side of a gorge near a waterfall-fed pool located in the hills of the Sahyadri mountains. Like all the locations of Buddhist caves, this one is located near main trade routes and spans six centuries beginning in the 2nd or 1st century B.C. A period of intense building activity at this site occurred under the Vakataka king Harisena between 460 and 478 A profuse variety of decorative sculpture, intricately carved columns and carved reliefs are found, including exquisitely carved cornices and pilaster. 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.

Later many Hindu kings from southern India patronize many cave temples dedicated to Hindu gods and goddesses. One such prominent example of cave temple architecture are the Badami Cave Temples at Badami, the early Chalukya capital, carved out in the 6th century. There are four cave temples hewn from the sides of cliffs, three Hindu and one Jain, that contain carved architectural elements such as decorative pillars and brackets as well as finely carved sculpture and richly etched ceiling panels. Nearby are many small Buddhist cave shrines.

Rock-cut architecture also developed with the apparition of stepwells in India, dating from 200–400 CE. Subsequently, the construction of wells at Dhank (550–625 CE) and stepped ponds at Bhinmal (850–950 CE) took place.

Rock cut temples continued to be excavated until the 12th century.
