A monolith is a geological feature consisting of a single massive stone or rock, or a single large piece of rock placed as, or within, a monument or building. In architecture, the term has overlap with megalith, normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, or for exceptionally large stones, such as obelisks, statues, monolithic columns, or large architraves. It may also be used of large glacial erratics moved by natural forces.
The word derives, via the Latin monolithus, from the Ancient Greek word μονόλιθος (monolithos), from μόνος ("one" or "single") and λίθος ("stone").
