In architecture, a cornice (from the Italian cornice meaning "ledge") is generally any horizontal decorative moulding that crowns a building or furniture element—for example, the cornice over a door or window, around the top edge of a pedestal, or along the top of an interior wall. A simple cornice may be formed just with a crown, as in crown moulding atop an interior wall or above kitchen cabinets or a bookcase.
A projecting cornice on a building has the function of throwing rainwater free of its walls. In residential building practice, this function is handled by projecting gable ends, roof eaves and gutters. However, house eaves may also be called "cornices" if they are finished with decorative moulding. In this sense, while most cornices are also eaves (overhanging the sides of the building), not all eaves are usually considered cornices. Eaves are primarily functional and not necessarily decorative, while cornices have a decorative aspect.
A building's projecting cornice may appear to be heavy and hence in danger of falling, particularly on commercial buildings, but often may actually be very light, made of pressed metal.

Cornice:
A cornice is a decorative architectural element that is typically found at the top of a building or structure, where the roof meets the walls. It is often a horizontal molding or projection that helps to protect the building from water damage and adds visual interest to the facade. Cornices can vary in design and complexity, ranging from simple to elaborate depending on the architectural style of the building.
