Modernism – Art-Nouveau. Various art forms in the Western world, at the turn of the 20th century, were influenced by the Art-Nouveau Style (Jugendstil in German) which was adopted by some Jerusalem architects during the 1920s and 1930s in the design of iron gates, window grilles, balustrades and railings. The characteristic patterns of Art-Nouveau are flowing lines, abstract or foliate curvilinear motifs, in natural-realistic or stylized shapes. Art-Nouveau style was prevalent mainly in the affluent Arab houses of Talbieh, Katamon and Baq’a Neighborhoods. Unfortunately, some of the ironwork illustrated in this chapter, was removed since the end of the 20th century. Many of the Art-Nouveau motifs which appear in this chapter, are also included in the fourth volume of this Guide “Modern 20th Century Design Identities”.
