or, more rarely, Italian Gothic. The facade is cliff-like, without any large projecting portico or pediment. There are several storeys with regular rows of windows which are generally differentiated between levels, and sometimes have pediments that are alternately triangular and segmental. The facade is symmetrical and usually has some emphasis around its centrally placed portal. The basement or ground floor is generally differentiated in the treatment of its masonry, and is often rusticated. The corners of early-19th-century examples generally have quoins or, in 20th-century buildings, there is often some emphasis that gives visual strength to the corners. Except in some Postmodern examples, there is always emphasis on the cornice, which may be very large and overhang the street. All public faces of the building are treated in a similar manner, the main difference being in the decoration of doors.
