"corbie step"的定义和意义

What is "corbie step"?

Corbie step is a type of stepped design used in the construction of gable ends, characterized by a series of horizontal projections or offsets. This architectural feature is typically made from stone or brick and is often found in medieval and traditional buildings, particularly in regions like Scotland. Corbie steps are used to support the roof while also adding a decorative element to the gable. The design helps with water drainage by directing rain away from the wall, reducing the risk of moisture damage. Overall, corbie steps combine functionality with aesthetic appeal in architectural design.
