In classical architecture, the architrave is the lowest section of the horizontal entablature. It acts as a lintel or beam that rests on the capitals of the vertical columns. It is generally topped with a frieze and cornice. The architrave varies corresponding to the distinguishing features of the main architectural orders – Doric, Ionic and Corinthian.
Architraves can also be found in building interiors. Here, an architrave is a moulding that sits above a door, window or other opening, where the architrave extends across the top of the side mouldings to the opening.
However, in the modern construction industry, the term architrave it is frequently used to refer to any horizontal or vertical moulding that forms the surround to a door, window or other opening, the purpose of which is to conceal the joints between the wall or ceiling and the timber casings that form the opening.
