In classical architecture, a pilaster is a rectangular support that resembles a flat column. It includes the usual features of a classical column; a capital at the top, the shaft of the column itself, a base and a plinth, but it usually only projects a third of its width or less from the wall.
Pilasters are traditionally used for decorative rather than structural purposes, often as a means of breaking up an otherwise empty expanse of wall. As with columns, different classical orders can be represented, and the surface of a pilaster can be left plain or can be fluted.
