Gathered around Art Nouveau (AN), a movement born in Europe in the late 19th century, 13 institutions from 10 countries joined in the project Art Nouveau & Ecology to study in a pan European and interdisciplinary perspective, the relation between Art Nouveau and the contemporary issue of ecology (E) through a series of actions, which encourage transnational mobility of workers and cultural objects and intercultural dialogue. The core action is a travelling exhibition AN & Nature which examines the processes of creation, from the raw materials and treatment in artistic workshops to the final art products. Innovative in its tactile aspect and aimed at the general public it is an ideal tool to promote AN in Europe and even outside and to increase awareness of heritage preservation. In 5 Historical labs, aimed to academics, students and AN amateurs, partners and specialists investigate different themes, related to AN and E. Exchange of knowledge and experiences are organised through bilateral and multilateral exchanges on specific topics connected with AN. Innovative laboratory (touchable chairs project aimed at visually impaired public) and pedagogical tools together with other outputs of the project bring art more accessible to disabled and children and assure the sustainability of the project through permanent education.The results of the project are disseminated through promotional activities on national and European levels. The most important is the international symposium Perception of AN in Brussels, to celebrate the 10th anniversary of Réseau Art Nouveau Network, which promotes the EU in its capital. Combining Art and E the project has double importance and actuality. It is conceived to answer queries, which were raised 100 years ago and are of great relevance today: how can art contribute to create a common European space in the culturally and politically diversified society and what we can learn from our predecessors to preserve our planet?
