Palazzo style refers to an architectural style of the 19th and 20th centuries based upon the palazzi (palaces) built by wealthy families of the Italian Renaissance. The term refers to the general shape, proportion and a cluster of characteristics, rather than a specific design; hence it is applied to buildings spanning a period of nearly two hundred years, regardless of date, provided they are a symmetrical, corniced, basemented and with neat rows of windows. "Palazzo style" buildings of the 19th century are sometimes referred to as being of Italianate architecture, but this term is also applied to a much more ornate style, particularly of residences and public buildings.

Architectural revivalism is the use of elements that echo the style of a previous architectural era that have or had fallen into disuse or abeyance between their heyday and period of revival. Revivalism, in a narrower sense, refers to the period of- and movement within- Western architectural history during which a succession of antecedent and remenescent styles were taken to by architects, roughly from the late 18th century, and which was itself succeeded by Modernism. Notable revival styles include Neoclassical architecture, and Gothic Revival. Revivalism is related to historicism.
