thumb|right|250px|Convent/nunnery of the Kalocsa School sisters named after Our Lady, Hungary. Built in 1860. Quadrifora is a type of four-light window. It appears in towers and belfries on top floors, where it is necessary to lighten the structure with wider openings. The quadrifora can also be a group closely set windows.

==Overview== The quadrifora is divided vertically in four parts by three small columns or pilasters, on which four arches rest, round or pointed. Sometimes, the quadrifora is framed by a further larger arch; the space among the arches may be decorated by a coat of arms or a small circular opening.
