In architecture, the horizontal moldings and bands supported by and located immediately above the columns of Classical buildings. The term also refers to similar structural supports in non-Classical buildings. The entablature is usually divided into three sections: the lowest band, or architrave, which originally took the form of a simple beam running from support to support; the central band, or frieze, consisting of an unmolded strip with or without ornament; the top band, or cornice, constructed from a series of moldings that project from the edge of the frieze. The styles of the entablature are different for the main orders of architecture: Doric, Ionic, and Corinthian. In the Doric order, it comprises the architrave above which were placed the alternating triglyphs and metopes. In the Ionic order, a continuous frieze was placed above the architrave.
