The National Romantic style was a Nordic architectural style that was part of the National Romantic movement during the late 19th and early 20th centuries. It is often considered to be a form of Art Nouveau. The National Romantic style spread across Denmark, Norway, Sweden, Finland, Estonia, and Latvia, as well as Russia, where it also appeared as Russian Revival architecture. Unlike some nostalgic Gothic Revival style architecture in some countries, Romantic architecture often expressed progressive social and political ideals, through reformed domestic architecture.
