Architrave

In classical architecture, an architrave (/ˈɑːrkɪtreɪv/; from Italian architrave 'chief beam', also called an epistyle;[1] from Ancient Greek ἐπίστυλον (epistylon) 'on the column') is the lintel or beam, typically made of wood or stone, that rests on the capitals of columns.

[2] The term can also apply to all sides, including the vertical members, of a frame with mouldings around a door or window.

The word "architrave" has come to be used to refer more generally to a style of mouldings (or other elements) framing a door, window or other rectangular opening, where the horizontal "head" casing extends across the tops of the vertical side casings where the elements join (forming a butt joint, as opposed to a miter joint).

In the Tuscan order, it only consists of a plain face, crowned with a fillet, and is half a module in height.

Examples: In contemporary architecture and interior design, the term architrave also refers to the mouldings that frame doors and windows.
