Réseau Art Nouveau Network

Through the use a scientific approach, it aims to keep professionals informed and to make the general public aware of the cultural significance and European dimension of the Art Nouveau heritage.

By 2017, the network included institutions in over 20 cities or regional areas to join together the best research and practices "essential to the effective preservation and promotion of our Art Nouveau heritage" and to create public events and a series of projects.

[1] Many Art Nouveau buildings throughout Europe are considered to be examples of the "remarkable architectural heritage" of various nations, and often these structures have historic monument protection designation.

As a professional, international consortium of institutions and cities, RANN conducts research as well as conservation efforts to preserve and promote Art Nouveau.

The exhibition was organized into three curatorial times: "vision, disappearance, and continuity and regeneration, or more accurately, hitherto unseen designs; no-longer-to-be-seen buildings; and projects seeking new uses."

The show received both praise and criticism, for example, Paris and Prague were not included although they both contain many works of Art Nouveau; a significant absence.
