Monolithic architecture

Buildings carved or excavated from a single material, usually rock

Monolithic architecture describes buildings which are carved, cast or excavated from a single piece of material, historically from rock. The most basic form of monolithic architecture is a rock-cut building, such as the monolithic churches of Ethiopia built by the Zagwe dynasty, or the Pancha Rathas in India. These are cut out of solid rock, to which they remain attached at the base. In most cases, this is evident from the remaining surrounding rock, but sometimes a building is cut from an outcrop, as in the Shore Temple in southern India, and only inspection at close quarters reveals that the building is monolithic.
