Architecture

The monasteries mostly consist of vihara halls for prayer and living, which are typically rectangular with small square dormitory cells cut into the walls, and by the second period a shrine or sanctuary at the rear centred on a large statue of the Buddha, also carved from the living rock. This change reflects the movement from Hinayana to Mahayana Buddhism. The other type of main hall is the narrower and higher chaitya hall with a stupa as the focus at the far end, and a narrow aisle around the walls, behind a range of pillars placed close together. Other plainer rooms were for sleeping and other activities. Some of the caves have elaborate carved entrances, some with large windows over the door to admit light. There is often a colonnaded porch or verandah, with another space inside the doors running the width of the cave.The central square space of the interior of the viharas is defined by square columns forming a more or less square open area. Outside this are long rectangular aisles on each side, forming a kind of cloister. Along the side and rear walls are a number of small cells entered by a narrow doorway; these are roughly square, and have small niches on their back walls. Originally they had wooden doors. The centre of the rear wall has a larger shrine room behind, containing a large Buddha statue. The viharas of the earlier period are much simpler, and lack shrines.Spink in fact places the change to a design with a shrine to the middle of the second period, with many caves being adapted to add a shrine in mid excavation, or after the original phase.

The plan of Cave 1 (right) shows one of the largest viharas, but is fairly typical of the later group. Many others, such as Cave 16, lack the vestibule to the shrine, which leads straight off the main hall. Cave 6 is two viharas, one above the other, connected by internal stairs, with sanctuaries on both levels.The four completed chaitya halls are caves 9 and 10 from the early period, and caves 19 and 26 from the later period of construction. All follow the typical form found elsewhere, with high ceilings and a central nave leading to the stupa, which is near the back, but allows walking behind it, as walking around stupas was (and remains) a common element of Buddhist worship (pradakshina). The later two have high ribbed roofs, which reflect timber forms, and the earlier two are thought to have used actual timber ribs, which have now perished.The two later halls have a rather unusual arrangement (also found in Cave 10 at Ellora) where the stupa is fronted by a large relief sculpture of the Buddha, standing in Cave 19 and seated in Cave 26. Cave 29 is a late and very incomplete chaitya hall.
