In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure.
A festoon, (originally a festal garland, Latin festum, feast) is a wreath or garland hanging from two points, and in architecture typically a carved ornament depicting conventional arrangement of flowers, foliage or fruit bound together and suspended by ribbons. The motif is sometimes known as a swag when depicting fabric or linen.
A finial or hip knob is an element marking the top or end of some object, often formed to be a decorative feature. In architecture, it is a small decorative device, employed to emphasize the apex of a dome, spire, tower, roof, gable, or any of various distinctive ornaments at the top, end, or corner of a building or structure.
In architecture, a mascaron ornament is a face, usually human, sometimes frightening or chimeric whose alleged function was originally to frighten away evil spirits so that they would not enter the building. The concept was subsequently adapted to become a purely decorative element. The most recent architectural styles to extensively employ mascarons were Beaux Arts and Art Nouveau.
A pediment is an architectural element found particularly in Classical, Neoclassical and Baroque architecture, and its derivatives, consisting of a gable, usually of a triangular shape, placed above the horizontal structure of the lintel, or entablature, if supported by columns. The tympanum, the triangular area within the pediment, is often decorated with relief sculpture. A pediment is sometimes the top element of a portico. For symmetric designs, it provides a center point and is often used to add grandness to entrances.
A rosette is a round, stylized flower design. The rosette derives from the natural shape of the botanical rosette, formed by leaves radiating out from the stem of a plant and visible even after the flowers have withered. The rosette design is used extensively in sculptural objects from antiquity, appearing in Mesopotamia, and in funeral steles' decoration in Ancient Greece. The rosette was another important symbol of Ishtar which had originally belonged to Inanna along with the Star of Ishtar. It was adopted later in Romaneseque and Renaissance architecture, and also common in the art of Central Asia, spreading as far as India where it is used as a decorative motif in Greco-Buddhist art.
A spire is a tall, slender, pointed structure on top of a roof or tower, especially at the summit of church steeples. A spire may have a square, circular, or polygonal plan, with a roughly conical or pyramidal shape. Spires are typically built of stonework or brickwork, or else of timber structure with metal cladding, ceramic tiling, shingles, or slates on the exterior.
In architecture, a turret is a small tower that projects vertically from the wall of a building such as a medieval castle. Turrets were used to provide a projecting defensive position allowing covering fire to the adjacent wall in the days of military fortification. As their military use faded, turrets were used for decorative purposes.
