Blind arcade

A blind arcade or blind window is an arcade that is composed of a series of arches that has no actual openings and that is applied to the surface of a wall as a decorative element: i.e., the arches are not windows or openings but are part of the masonry face.[1] It is designed as an ornamental architectural element and has no load-bearing function. Whereas a blind arch is usually a single arch or a series of joined arches as a frieze (sometimes called Lombard band), a blind arcade is composed of a series of arches that have well-defined columns.
