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, tombs, and cave dwellings.

A rock relief or rock-cut relief is a relief sculpture carved on solid or "living rock" such as a cliff, rather than a detached piece of stone. They are a category of rock art, and sometimes found as part of, or in conjunction with, rock-cut architecture. However, they tend to be omitted in most works on rock art, which concentrate on engravings and paintings by prehistoric peoples. A few such works exploit the natural contours of the rock and use them to define an image, but they do not amount to man-made reliefs. Rock reliefs have been made in many cultures throughout human history, and were especially important in the art of the ancient Near East. Rock reliefs are generally fairly large, as they need to be in order to have an impact in the open air. Most of those discussed here have figures that are over life-size, and in many the figures are multiples of life-size.
