An acroterion, acroterium, (pl. akroteria) 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. 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. They are sometimes incorporated into furniture designs.
According to Webb, during the Hellenistic period the winged victory or Nike figure was considered to be "the most appropriate motif for figured akroteria.”
