Quoins

- stones larger or better shaped, than those of which a wall is composed, used to form the corners of walls or door and window openings. Laid in an arrangement of headers and stretchers on alternate courses, this gives strength to the build, and allows the facework of the walling to tooth into the corner. If quoins project they are described as raised, and if provided with chamfered angles, rusticated. Quoins are said to be squint when they are not at right angles. A squared stone, the same height as a quoin and immediately next to it can be referred to as a second quoin.
