Renaissance Revival is a broad designation that covers many 19th century architectural revival styles which were neither Grecian nor Gothic but which instead drew inspiration from a wide range of classicizing Italian modes. Under the broad designation "Renaissance architecture" nineteenth-century architects and critics went beyond the architectural style which began in Florence and central Italy in the early 15th century as an expression of Humanism; they also included styles we would identify as Mannerist or Baroque. Self-applied style designations were rife in the mid- and later nineteenth century: "Neo-Renaissance" might be applied by contemporaries to structures that others called "Italianate", or when many French Baroque features are present.
