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.

The Free Trade Hall on Peter Street, Manchester, England, was constructed in 1853–56 on St Peter's Fields, the site of the Peterloo Massacre. It is now a Radisson hotel.
