In classical architecture, a cornice describes an area or space that overhangs something else. It is the uppermost horizontal area that projects out over the top of a wall or below a roof line. A cornice is a common feature of ancient Greek and Roman architecture, where it is the uppermost part of the entablature.

Traditionally, the cornice is made up of the following elements:

The function of the cornice is to protect the structure’s walls by directing rainwater away from the building, although its traditional function is also decorative.

The cornice is also common in interiors where it is a type of moulding that runs along the top of interior walls. It can assist with brightening a room by reflecting light into areas of shadow, and can make small rooms seem larger by drawing the eye upwards. It can also be used to help conceal cracking that may occur along the join between walls and ceilings.

The term 'cornice' may also be used to refer to an overhanging strip above items of furniture such as kitchen cupboards.

An interior cornice can be plain or highly decorative as in these examples from a Scottish manse.

Plain cornice may be referred to as ‘coving’.

The most common materials for cornices are timber, paper-covered plaster, polyurethane, expanded polystyrene, plaster and medium density fibreboard (MDF).

Window cornices are box-like structures placed over windows to conceal the strings and other attachments of shades or curtains (also known as a pelmet). Door cornices may be used over a door frame for decorative purposes. Sometimes this maybe referred to as an architrave.
