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.
