cornicing

Cornicing is a decorative architectural element that projects horizontally from the top of a wall or building. It serves both aesthetic and functional purposes. Aesthetically, cornices add visual interest and a sense of completion to the exterior or interior of a structure, breaking up the monotony of plain walls and roofs. They can vary greatly in style, from simple, unadorned bands to elaborately carved profiles featuring moldings, dentils, and other ornamental details.

Functionally, cornices provide a transition between the wall and the roofline. In exterior applications, they can help to direct rainwater away from the building's facade, protecting the walls from water damage and erosion. The overhang of the cornice can also offer shade to windows and doors, reducing solar heat gain in warmer months. Historically, cornices were often constructed from stone, brick, or wood. In modern construction, materials such as stucco, concrete, plaster, or metal are also commonly used. The specific design and material of a cornice can reflect the architectural style of the building, contributing to its overall character and historical context. Interior cornices, often referred to as crown molding, serve a similar decorative purpose, softening the transition between walls and ceilings.
