An acroterion, acroterium, (pl. akroteria)[1] is an architectural ornament placed on a flat pedestal called the acroter or plinth, and mounted at the apex or corner of the pediment of a building in the classical style.[2] An acroterion placed at the outer angles of the pediment is an acroterion angularium (angulārium means ‘at the corners’).
The acroterion may take a wide variety of forms, such as a statue, tripod, disc, urn, palmette or some other sculpted feature. Acroteria are also found in Gothic architecture.[3] They are sometimes incorporated into furniture designs.[4]
