An entablature, in classical Greek and Roman architecture, is a
three-part structure resting atop a series of columns or pilasters.
Traditionally, entablatures were made of stone, but they can
also be constructed of masonry or wood.
The lowest part of an entablature is the architrave, the beam
that sits directly atop the columns or pilasters.
Above the architrave is the frieze, a horizontal band that’s
often decorated with carvings.
The topmost element of the entablature is the cornice, a decorative,
horizontal molding (or series of moldings) that crowns a
structure. Cornices often project several inches or more from the
top of a building in order to protect the façade from rain.
While an entablature generally forms part of a building’s
exterior, the entablature form may also be applied to furniture,
mantels, and other interior projects.
