Art Nouveau (, anglicised /ˈɑːt nuːvəu/) (French for 'new art') is an international style of art, architecture and design that peaked in popularity at the beginning of the 20th century (1880-1914) and is characterised by highly-stylised, flowing, curvilinear designs often incorporating floral and other plant-inspired motifs.
The name 'Art Nouveau' derived from the name of a shop in Paris, Maison de l'Art Nouveau, at the time run by Siegfried Bing, that showcased objects that followed this approach to design. The style introduced by Bing was not an immediate success in Paris but rapidly spread to Nancy and to Belgium (especially Brussels) where Victor Horta and Henry Van de Velde would make major contributions in the field of architecture and design. In the United Kingdom Art Nouveau developed out of the Arts and Crafts Movement. The most important centre in Britain was Glasgow with the creations of Charles Rennie Mackintosh.
More localised terms for the phenomenon of self-consciously radical, somewhat mannered reformist chic that formed a prelude to 20th-century modernism include Jugendstil in Germany, Austria and many other countries or skønvirke in Denmark, named after the avant-garde periodical Jugend ('Youth'), Młoda Polska ('Young Poland' style) in Poland, and Sezessionsstil ('Secessionism') in Vienna, where forward-looking artists and designers seceded from the mainstream salon exhibitions to exhibit on their own work in more congenial surroundings.
In Spain, the movement was centred in Barcelona and was known as modernisme, with the architect Antoni Gaudí as the most noteworthy practitioner. Art Nouveau was also a force in Eastern Europe, with the influence of Alfons Mucha in Prague and Moravia (part of the modern Czech Republic) and Latvian Romanticism (Riga, the capital of Latvia, is home to over 800 Art Nouveau buildings).
In Russia, the movement revolved around the art magazine Mir iskusstva ('World of Art'), which spawned the revolutionary Ballets Russes. In Italy, Stile Liberty was named for the London shop, Liberty & Co, which distributed modern design emanating from the Arts and Crafts movement, a sign both of the Art Nouveau's commercial aspect and the 'imported' character that it always retained in Italy.
The entrances to the Paris Métro designed by Hector Guimard in 1899 and 1900 are famous examples of Art Nouveau in Paris.
