The word 'spandrel' is typically used to refer to the roughly triangular space or surface that is found between a curved figure and a rectangular boundary. It is thought to derive from from the Old French word 'spandre', meaning to spread.
Spandrels can be found in a number of situations:
- The space between the curve of an arch and a rectilinear moulding.
- The space bounded by adjacent arches in an arcade and the horizontal moulding above.
- The space, where arches adjoin, between their crowns and springing lines. This is called a 'spandrel wall' if it is filled in.
- The space under a flight of stairs.
The term spandrel may also be used to refer to the space between the sill of a window on one storey, and the head of the window beneath it. A spandrel panel is the term given to a sculpted or other decorative element used in this space. If the space is filled with opaque or translucent glass, it is referred to as spandrel glass.
