Masonry blocks at the corner of a wall
Quoining on the corners of Palazzo Aragona Gonzaga, Rome Alternate horizontal quoining on a wall in East Ayrshire Porch quoins, Palazzo Giusti, VeronaQuoins ( or ) are masonry blocks at the corner of a wall.[1] Some are structural, providing strength for a wall made with inferior stone or rubble,[2] while others merely add aesthetic detail to a corner.[3] According to one 19th-century encyclopedia, these imply strength, permanence, and expense, all reinforcing the onlooker's sense of a structure's presence.[4]
Stone quoins are used on stone or brick buildings. Brick quoins may appear on brick buildings, extending from the facing brickwork in such a way as to give the appearance of generally uniformly cut ashlar blocks of stone larger than the bricks. Where quoins are decorative and non-load-bearing a wider variety of materials is used, including timber, stucco, or other cement render.
Rustic quoins and keystone on the main entrance to the Palazzo Giusti, VeronaIn a traditional, often decorative use, large rectangular ashlar stone blocks or replicas are laid horizontally at the corners. This results in an alternate, quoining pattern.
Alternate cornerstones[edit]Courses of large and small corner stones are used, alternating between stones of different thickness, with typically the larger cornerstones thinner than the smaller.[citation needed]
Alternate vertical[edit] Tower of St Bene't's, Cambridge, showing long and short work[5]The long and short quoining method instead places long stone blocks with their lengths oriented vertically, between smaller ones that are laid flat. This load-bearing quoining is common in Anglo-Saxon buildings such as St Bene't's Church in Cambridge, England.[5]
