We invite you on this audio walk to discover Marburg's connections with Eastern Europe over eight centuries, using authentic buildings throughout the city. But what does "authentic" mean? And why is it important to us today that a building, a quote, or a description is genuine and credible? Let's find out together! This project is brought to you by the Herder Institute for Historical Research on East Central Europe as part of the Leibniz Research Alliance on Historical Authenticity/Value of the Past, funded by the Leibniz Research Alliance "Value of the Past." The narrators are Anne Schirmacher and Michel Diercks, with music by Jacke Schwarz. Coordination was handled by Antje Coburger, while the research and texts were provided by Antje Johanning-Radžienė, Heidi Hein-Kircher, Jürgen Warmbrunn, and Antje Coburger. Editing, sound, and direction were managed by Johanna Tirnthal, Tim Schleinitz, Constantin Hühn, and Diana Köhler for audiokombinat.net. The images are by Claudia Junghänel. Production: Leibniz Center for Contemporary History Potsdam, 2022.
