Different topics are introduced during leisurely walks around the city. Personalities such as digital expert Tijen Onaran, Petra von Strombeck, head of New Work SE, the pianist, Igor Levit, the climate activist, Luisa Neubauer, and Thomas Madreiter, Head of Urban Planning in Vienna, are among those who have gone on these walking tours. "We did not simply want to set out theses, but to come up with exciting, sometimes controversial comments during eight themed walks and then put the topics up for discussion," said Vöpel. Physical exercise should go hand in hand with intellectual finesse. The idea is to let thoughts flow freely, let sensual, emotional and atmospheric impressions take effect and put the experience into words. The resulting pool of facts and ideas is then discussed and developed by society as a whole in Hamburg.
