Bay
THEORY & MATHEMATICSintermediate
Definition
A subdivision of a building's interior or exterior, typically defined by a recurring structural or spatial module. Bays are created by columns, walls, or posts and give rhythm to a facade or interior. A 'bay window' is a window that projects outward from the wall.
Example
Romanesque cathedrals like Durham Cathedral (1093) are organized into a series of bays defined by massive columns and arches, creating rhythm and supporting the vault structure.
