Acroterion
（重定向自Acroteria）
An acroterion or acroterium is an architectural ornament placed on a flat base called the acroter or plinth, and mounted at the apex of the pediment of a building in the classical style. It may also be placed at the outer angles of the pediment; such acroteria are referred to as acroteria angularia (angulāria means ‘at the corners’).
