 The competing neo-Gothic style however rose to popularity during the early 1800s, and the later part the 19th century was characterised by a variety of styles, some of them only slightly or not at all related to classicism (such as Art Nouveau), and Eclecticism.Although classical architecture continued to play an important role and for periods of time at least locally dominated the architectural scene, as exemplified by the Nordic Classicism during the 1920s, classical architecture in its stricter form never regained its former dominance.With the advent of Modernism during the early 20th century, classical architecture arguably almost completely ceased to be practised.
