Across all the mountains, Johannes Schweikle and Daniel Keyerleber embark on a journey. The author and the photographer explore the question: What is home? Together, they follow the Westweg, a 285-kilometer trail from Pforzheim to Basel. The red diamond symbol guides them from the Führerbunker to the cabin of philosopher Martin Heidegger. They dine with a Michelin-starred chef and discover the origins of the cherry cake. In the forest, they pick up the trail of a wolf that threatens farmers and their livestock. An ancient fir tree, which has survived all disasters, awaits them in the heart of the Central Massif of German sentiment.
