In masonry, what is the term for elements protruding successively from the face of a structure?

The term for elements that protrude successively from the face of a structure is known as corbel. In masonry, corbeling is a technique where blocks, stones, or bricks are laid in a manner that they project outwards, creating a term that often serves both a structural and decorative purpose.

Corbels can be found in various architectural elements such as cornices, arches, and eaves, where they not only add aesthetic appeal but also help support weight, like that of a roof or some architectural feature above. This technique allows for creating overhangs and is often used in historical and modern masonry work to enhance the visual impact of a structure.

Understanding corbeling is key in masonry as it relates to how structures are built to accommodate loads while also being visually appealing.
