It just does not work without skilled craftsmen, producers of signs, and neon installations. For the 2020 Luminale there will be 20 light fixtures illuminating the Light Walk between Bethmann pond and the Rechneigrabenweiher. The black and white lanterns in the design of the Luminale guide the view to the existing light fixtures in the historical embankment park. This demonstrates that skilled craftsmanship, literally the next door economic power, stands for tradition but far more is a brand name for future and innovation. With this unique dual training, licensed craftsmen are indispensable for urban design, digitalization, smart construction, and sustainability.
