In architecture, both the external corner of a building and, more often, one of the stones used to form that corner.These stones are both structural and decorative in that they often differ in jointing, colour, texture, or size from the masonry of the adjoining walls. Usually quoins are toothed (i.e., set in short courses in a regular pattern of alternating lengths). Such construction dates back to ancient Rome.* * *
in Western architecture, both the external angle or corner of a building and, more often, one of the stones used to form that angle. These cornerstones are both decorative and structural, since they usually differ in jointing, colour, texture, or size from the masonry of the adjoining walls.Most frequently quoins are toothed, set in a regular pattern of alternating lengths. Such toothed construction was used at external corners of brick or stone buildings in ancient Rome. In 17th-century France, quoins were heavily rusticated, their surfaces roughened and their joints recessed. Similar treatment was used around wall openings (windows, doorways, and arches).Occasionally quoins are dressed, smooth stones to contrast with walls of rough rubble masonry. They may also be of massive size, as in some Italian Renaissance palaces. Quoins in some brick buildings are covered with plaster, which accounts for the sharp contrast between the stark white quoins and dark brick walls of many manor houses built in the English Renaissance style.* * *
