Placed on a green field at the Freiburg airfield, the cantilevering altar was built without a single drop of glue and without any kind of welding. Instead, only bolted, rotating, and clamp joints were used, which allowed for quick assembly and even faster disassembly. Almost all of the materials can be re-assembled elsewhere.
The steel support is covered in laminar wood, while the rear wall and roof were covered in PVC Polyester fabric panels. In order to support the cantilever, which rises 15 meters above the ground, Werner Sobek employed techniques commonly used to build temporary bridges. Even the furniture used to seat participants was saved from a 2006 Papal visit – reflecting a genuine commitment to reducing waste. Dare we say holy cow? This is awesome.
