A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains, or a single large piece of rock placed as, or within, a monument or building. Erosion usually exposes the geological formations, which are often made of very hard and solid metamorphic or igneous rock.

In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces.

The Pallava dynasty existed between the 3rd and 9th centuries CE, ruling a portion of what is today southern India. They gained prominence after the eclipse of the Satavahana dynasty, whom the Pallavas served as feudatories. A number of legends are associated with their origin.

The Pallavas were instrumental in the transition from rock-cut architecture to stone temples. The earliest examples of Pallava constructions are rock-cut temples dating from 610–690 CE and structural temples between 690–900 CE. A number of rock-cut cave temples bear the inscription of the Pallava king, Mahendravarman I and his successors.

Among the accomplishments of the Pallava architecture are the rock-cut temples at Mahabalipuram. There are excavated pillared halls and monolithic shrines known as rathas in Mahabalipuram. Early temples were mostly dedicated to Shiva. The Kailasanatha temple in Kanchipuram and the Shore Temple built by Narasimhavarman II, rock cut temple in Mahendravadi by Mahendravarman are fine examples of the Pallava style temples. The temple of Nalanda Gedige in Kandy, Sri Lanka is another. The famous Tondeswaram temple of Tenavarai and the ancient Koneswaram temple of Trincomalee were patronized and structural
