Art Nouveau religious buildings

Art Nouveau temples are churches, chapels, synagogues, and mosques built in the style known as Art Nouveau in French and English languages (also Modern Style or Glasgow style in the latter one), Jugendstil in Germany and Nordic countries, Secessionsstil in countries of former Austro-Hungary, Modernisme in Catalan, Modern in Russian, Stile Liberty or Stile Floreale in Italian. As National Romantic style is also referred to Art Nouveau, churches of that style are also listed here, as well as some temples not of pure Art Nouveau style but with distinctive Art Nouveau features.
