This modest booklet examines the architecture of the new Experimenta Science Centre in Heilbronn from three different angles: In terms of urban history, this building - which was designed by sauerbruch hutton - simultaneously stands as an icon and a tool for change that accompanies its city into a new economy of knowledge. As a construction, it follows its own experimental path, both in organisational, structural and ecological terms. Finally, the project is a late offspring of a typological family of spiral buildings which stretches from antiquity via the modern movement up to the very present. All three perspectives are captured in Florian Heilmayer's concise and lucid texts and are illustrated by numerous photos and drawings. Both for Experimenta visitors as well as other interested contemporaries this little pamphlet is a must.
