Originally, the area of responsibility for landscape architecture was based on the premise that the planning and creating of open spaces such as parks and gardens was the business of garden artists. Today, the training of landscape architects and future challenges of the profession include the protection of natural resources and the environment, urban planning or tourism - to name but a few. The international symposium "From Garden Art to Landscape Architecture - Traditions, Re-Evaluations, and Future Perspectives" addressed questions which, based on the idea of garden art, should help to reconstruct its historical development but also discussed the notion and the relevance of "art" in everyday work. The contributions critically reflect on the professional self-image of landscape architects at the beginning of the 21st century. The symposium in September 2018 was co-organized by the City and State Capital of Hannover's Herrenhausen Gardens Division, the Deutsche Gesellschaft für Gartenkunst und Landschaftsarchitekturt (DGGL), the Volkswagen Foundation and the Centre of Garden Art and Landscape Architectur.
