Berlin is full of crazy ideas and characters, but who walks around the city? Jörg Liemann has done it, covering 234 kilometers plus detours, and he lets us join him. At first, it's simply about discovering: What is out there? But soon he meets, for example, a mapmaker, the mayor of Spandau accompanies him for part of the journey, Jörg Liemann visits the forester of Grossbeeren, and the writer Rolf Schneider, who still lives right on the border. He strolls with the castellan over Peacock Island and then hops over to the Bundeswehr. The travelogue is enlivened and enriched by 240 black-and-white photos, 45 miniature maps for orientation, and three special maps.
