What does corbeling mean?
Corbeling is a masonry technique in which each successive course of brick or stone is laid so that it projects slightly beyond the course beneath it, allowing a wall to carry an overhanging load without beams or external supports. The result — a staircase-like series of offset blocks known as corbels — has been used since ancient times to widen chimneys above rooftops, support parapets, extend upper stories over streets, and form the springing point of arches. Because each layer bears only on the one below through compression, well-executed corbeling can be remarkably strong despite its seemingly precarious geometry. The term belongs chiefly to the vocabulary of architects, builders, and architectural historians, appearing in discussions of medieval castles, Tudor chimneys, and traditional brickwork. Its enduring appeal lies in the way it turns a simple principle of stacked offsets into strikingly bold projections that have survived centuries of weather.
nounCorbeling is a masonry technique in which successive courses of brick or stone project progressively outward from a wall to support an overhanging structure such as a chimney, parapet, or upper story. It also denotes the set of corbels so constructed.
- Masonry construction in which each course projects slightly beyond the one below, allowing a wall to support an overhang without external bracing.
- The projecting structure or series of corbels produced by this method.
"The medieval tower's chimney was carried on stepped corbeling that jutted boldly from the stone facade."
"The builder used brick corbeling to widen the chimney where it passed above the roofline."
"Medieval builders relied on corbeling to extend upper stories out over narrow streets."
The word 'corbel' comes from the Old French name for a crow — so every projecting stone corbel is, etymologically, a little raven perched on your wall.

Etymology of corbeling
The word derives from 'corbel', borrowed in the Middle Ages from Old French, where it meant a crow or raven — a bird whose perched silhouette suggested the shape of a projecting bracket. The French term traces back through Late Latin forms related to 'corvus', the Latin word for raven, making 'corbeling' a distant cousin of words like 'corvine' and 'corvid'. The technique itself is far older than the word, appearing in ancient Egyptian, Mayan, and medieval European construction long before it acquired its English name.

How corbeling is actually used
Primarily a technical term of architecture and building trades, encountered in architectural history, restoration work, and construction writing rather than everyday speech.
Easily confused with corbeling
A cantilever is a rigid structural element anchored at only one end that projects into space, whereas corbeling achieves projection by stacking progressively offset courses of masonry.
