While the beginning of Neo-Renaissance period can be defined by its simplicity and severity, what came later was far more ornate in its design. This period can be defined by some of the great opera houses of Europe, such as Gottfried Semper's Burgtheater in Vienna, and his Opera house in Dresden. This ornate form of the Neo-Renaissance, originating from France, is sometimes known as the "Second Empire" style, by now it also incorporated some Baroque elements. By 1875 it had become the accepted style in Europe for all public and bureaucratic buildings. In England, where Sir George Gilbert Scott designed the London Foreign Office in this style between 1860 and 1875, it also incorporated certain Palladian features.
