The Art Nouveau movement, developed in Europe at the end of the 19th and the beginning of the 20th century, touched many cities and regions and took various forms. 
In 1999, a network of European cities possessing a rich Art Nouveau heritage in architecture and decorative arts was formed. In total, this network unites 14 cities whose chief objective is to protect and promote the Art Nouveau heritage. This project receives the financial support of the European community and organizes numerous projects to raise and promote awareness of Art Nouveau. Publications, the creation of a web site, expositions, photo reports, and inventories of items help promote Art Nouveau’s acknowledged, researched, and documented but often threatened heritage.
This network is also intended to work as a means of exchanging information between partnering cities.
The city of Nancy participated in the formation of this network in 1999 and since then has remained an active member.
