Archivolt

An archivolt is an ornamental molding or band following the curve of the underside of an arch. It is composed of architectural elements, often moldings, that run along the face of an arch and frame an arched opening. The archivolt is the counterpart to the architrave, which runs horizontally across the top of columns or piers. The term can also refer to the entire arched frame, including the molding and any decorative elements within it.

Typically, an archivolt is composed of several bands or moldings, each projecting slightly beyond the one below, creating a layered effect. These moldings can be simple and plain, or highly elaborate and decorated with carvings, reliefs, or other ornamentation. The design and complexity of the archivolt often reflect the architectural style of the building in which it is found. Common materials used for archivolts include stone, brick, and plaster.

The archivolt serves both a structural and decorative function. Structurally, it helps to define the shape and boundaries of the arch. Decoratively, it enhances the visual appeal of the arch and adds richness and detail to the facade of a building. Archivolts are commonly found in Romanesque, Gothic, and Renaissance architecture, as well as in other architectural styles that incorporate arches.
