Art Nouveau emerged between 1890 and 1910 as one of Europe's most influential architectural and decorative movements. Architects of this period broke from historical precedents to develop a new visual language characterized by curved lines, plant motifs and richly ornamented facades. The movement took different names across countries: Modernisme in Catalonia, Jugendstil in German-speaking regions, Secession in Austria and Liberty in Italy. This diversity led to regional interpretations that incorporated local craft traditions and cultural characteristics. This collection includes buildings across Barcelona, Paris, Budapest, Vienna, Prague, Brussels and other European cities. In Barcelona, works by Antoni Gaudí and his contemporaries shape entire streetscapes, including Casa Batlló with its undulating facade and the Sant Pau Recinte Modernista. Paris preserves the celebrated metro stations by Hector Guimard, while Budapest features the Gresham Palace, Museum of Applied Arts and Gellért Baths. Vienna presents characteristic examples of the Austrian variant with the Secession Building and Majolica House. The collection also includes less visited sites such as the Kőrössy Villa in Kecskemét, Horta Museum in Brussels and the railway station in Helsingør, Denmark.
