A gable is an architectural element that can be found particularly in classical, neoclassical and baroque architecture. Its derivatives consist of a pediment, usually triangular in shape, placed above the horizontal structure of the lintel or entablature when supported by pillars. The tympanum, the triangular area within the pediment, is often decorated with relief sculptures. A gable is sometimes the top element of a portico. In symmetrical designs, it provides a center point and is often used to add size to entrances.


The pediment is found in classical Greek temples, Etruscan, Roman, Renaissance, Baroque, Rococo, Neoclassical and Beaux-Arts architectures. A prominent example is the Parthenon, in which there is a tympanum decorated with figures in relief sculptures. This architectural element was developed in the architecture of ancient Greece and first appeared as the gable ends of Greek temples. In ancient Rome, the Renaissance, and later architectural revivals, the pediment was used as a non-structural element over windows, doors, and aedicules. Some protected windows and openings from the elements. When classical architecture moved to Britain during the Renaissance, gables mismatched the steep roofs and peeled away from the structure just to make an impression. The shape of the gable is determined by the main function of the roof, which in several areas is the drainage of rainwater.

A variant is the "segment" - or "arch" gable, in which the normal angular bevels of the cornice are replaced by one in the form of a segment of a circle in the manner of a depressed arch. Both traditional and segmental gables have "broken" and "open" shapes. in the broken gable the rake cornice remains open at the top. The open gable is open along the base - often "sculpture", "tondo" painting, mirror or window. These forms were adopted into Mannerist architecture and applied to furniture designed by Thomas Chippendale. The terms "open gable" and "broken gable" are often used synonymously. Another variant is that Neck gable of Swan's and a refinement of a broken pediment with two S-shaped profiles that resemble a gooseneck. Non-triangular variations of gables are usually found above doors, windows, and porches.
