The term 'Projecting Corner' is a type of architectural feature that is used to provide structural support and decorative detail. It is composed of two parts: a coign, which is a stone block that projects from the corner of a building, and an ANGLE, which is a piece of metal or wood that is used to join two pieces of material together. Together, these two components form a projecting corner that can be used to add visual interest and structural stability to a building.
