Architrave

1. In classical architecture, a simple, flat, structural lintel spanning an opening in a wall. The architrave is the lowest part of an entablature resting upon the abacus (flat slab) on the capital of a column.

2. The moulding around the exterior of an arch or the various parts surrounding a door or window. An eared architrave has the surround turning outwards, then upwards before returning horizontally along the top of the opening it is framing.
