Indian rock-cut architecture in the context of "Rock relief"

Vihāra generally refers to a Buddhist temple or Buddhist monastery for Buddhist renunciates, mostly in the Indian subcontinent. The concept is ancient and in early Pali texts, it meant any arrangement of space or facilities for dwellings. The term evolved into an architectural concept wherein it refers to living quarters for monks with an open shared space or courtyard, particularly in Buddhism. The term is also found in Jain monastic literature, usually referring to temporary refuge for wandering monks or nuns during the annual Indian monsoons. In modern Jainism, the monks continue to wander from town to town except during the rainy season (chaturmasya), and the term "vihara" refers to their wanderings.

Vihara or vihara hall has a more specific meaning in the architecture of India, especially ancient Indian rock-cut architecture. Here it means a central hall, with small cells connected to it, sometimes with beds carved from the stone. Some have a shrine cell set back at the centre of the back wall, containing a stupa in early examples, or a Buddha statue later. Typical large sites such as the Ajanta Caves, Aurangabad Caves, Karli Caves, and Kanheri Caves contain several viharas. Some included a chaitya or worship hall nearby. The vihara originated as a shelter for monks when it rains.

Rock-cut architecture is the creation of structures, buildings, and sculptures by excavating solid rock where it naturally occurs. Intensely laborious when using ancient tools and methods, rock-cut architecture was presumably combined with quarrying the rock for use elsewhere. In India and China, the terms cave and cavern are often applied to this form of man-made architecture, but caves and caverns that began in natural form are not considered to be rock-cut architecture even if extensively modified.

Although rock-cut structures differ from traditionally built structures in many ways, many rock-cut structures are made to replicate the facade or interior of traditional architectural forms. Interiors were usually carved out by starting at the roof of the planned space and then working downward. This technique prevents stones falling on workers below. The three main uses of rock-cut architecture were temples (like those in India), tombs, and dwellings (like those in Cappadocia).

Khmer architecture (Khmer: ស្ថាបត្យកម្មខ្មែរ), also known as Angkorian architecture (Khmer: ស្ថាបត្យកម្មសម័យអង្គរ), is the architecture produced by the Khmer during the Angkor period of the Khmer Empire from approximately the later half of the 8th century CE to the first half of the 15th century CE.

The architecture of the Indian rock-cut temples, particularly in sculpture, had an influence on Southeast Asia and was widely adopted into the Indianised architecture of Cambodian (Khmer), Annamese and Javanese temples (of the Greater India). Evolved from Indian influences, Khmer architecture became clearly distinct from that of the Indian sub-continent as it developed its own special characteristics, some of which were created independently and others of which were incorporated from neighboring cultural traditions, resulting in a new artistic style in Asian architecture unique to the Angkorian tradition. The development of Khmer architecture as a distinct style is particularly evident in artistic depictions of divine and royal figures with facial features representative of the local Khmer population, including rounder faces, broader brows, and other physical characteristics. In any study of Angkorian architecture, the emphasis is necessarily on religious architecture, since all the remaining Angkorian buildings are religious in nature. During the period of Angkor, only temples and other religious buildings were constructed of stone.

A chaitya, chaitya hall, chaitya-griha, (Sanskrit:Caitya; Pāli: Cetiya) refers to a shrine, sanctuary, temple or prayer hall in Indian religions. The term is most common in Buddhism, where it refers to a space with a stupa and a rounded apse at the end opposite the entrance, and a high roof with a rounded profile. Strictly speaking, the chaitya is the stupa itself, and the Indian buildings are chaitya halls, but this distinction is often not observed. Outside India, the term is used by Buddhists for local styles of small stupa-like monuments in Nepal, Cambodia, Indonesia and elsewhere. In Thailand a stupa itself, not a stupa hall, is called a chedi, a local Thai word derived from the Pali Cetiya. In the historical texts of Jainism and Hinduism, including those relating to architecture, chaitya refers to a temple, sanctuary or any sacred monument.

Most early examples of chaitya that survive are Indian rock-cut architecture. Scholars agree that the standard form follows a tradition of free-standing halls made of wood and other plant materials, none of which has survived. The curving ribbed ceilings imitate timber construction. In the earlier examples, timber was used decoratively, with wooden ribs added to stone roofs. At the Bhaja Caves and the "Great Chaitya" of the Karla Caves, the original timber ribs survive; elsewhere marks on the ceiling show where they once were. Later, these ribs were rock-cut. Often, elements in wood, such as screens, porches, and balconies, were added to stone structures. The surviving examples are similar in their broad layout, though the design evolved over the centuries.

Indian architecture is rooted in the history, culture, and religion of India. Among multiple architectural styles and traditions, the best-known include the many built in accordance to Indian religion and philosophy with Hindu, Jain, Buddhist, and Sikh styles of architecture being the most prevalent in India, with Indo-Islamic architecture, Rajput architecture, Mughal architecture, South Indian architecture, and Indo-Saracenic architecture having a strong presence as well.

Early Indian architecture was made from wood, which did not survive due to rotting and instability in the structures. Instead, the earliest surviving examples of Indian architecture are Indian rock-cut architecture, including many Buddhist, Hindu, and Jain temples.

The Karla Caves, Karli Caves, Karle Caves or Karla Cells, are a complex of ancient Buddhist Indian rock-cut caves at Karli near Lonavala, Maharashtra. It is just 10.9 Kilometers away from Lonavala. Other caves in the area are Bhaja Caves, Patan Buddhist Cave, Bedse Caves and Nasik Caves.The shrines were developed over the period from the 2nd century BCE to the 5th century CE. The oldest of the cave shrines is believed to date back to 160 BCE, having arisen near a major ancient trade route, running eastward from the Arabian Sea into the Deccan.

The group at Karla is one of the older and smaller of the many rock-cut Buddhist sites in Maharashtra. It is one of the best-known because of the famous "Grand Chaitya" (Cave 8), the largest and most completely preserved chaitya hall of the period, containing unusual quantities of fine sculpture on a large scale.

The Kanheri Caves (Kānherī-guhā [kaːnʱeɾiː ɡuɦaː]) are a group of caves and rock-cut monuments, cut into a massive basalt outcrop in the forests of the Sanjay Gandhi National Park, on the island of Salsette in the western outskirts of Mumbai, India. They contain Buddhist sculptures and relief carvings, paintings and inscriptions, dating from the 1st century CE to the 10th century CE. Kanheri comes from the Sanskrit Krishnagiri, which means "black mountain".

The site is on a hillside, and is accessible via rock-cut steps. The cave complex comprises one hundred and nine caves. The oldest are relatively plain and unadorned, in contrast to later caves on the site, and the highly embellished Elephanta Caves of Mumbai. Each cave has a stone plinth that functioned as a bed. A congregation hall with huge stone pillars contains a stupa (a Buddhist Pagoda). Rock-cut channels above the caves fed rainwater into cisterns, which provided the complex with water. Once the caves were converted to permanent monasteries, their walls were carved with intricate reliefs of Buddha and the Bodhisattvas. Kanheri caves were built in the 1st century and had become an important Buddhist settlement on the Konkan coast by the 3rd century CE.
