Immerse yourself in the fascinating world of science and go on a journey in time through “Germany’s Oxford”, now the Dahlem Campus in Berlin. Ten stations tell stories about the former research institutes of the Kaiser Wilhelm Society (now the Max Planck Society) and about the people who made pioneering discoveries there. Only rarely over the course of history have so many Nobel Prize winners lived and worked in a world created for them. On your tour you will experience the special atmosphere that characterises Dahlem and its campus to this day. You will travel through time and space, meet the past in the present, and gain a lively impression of outstanding achievements of modern research. Accompany Otto Hahn and Lise Meitner as they discover nuclear fission and listen to the story of their unusual friendship that survived two world wars and a regime of terror. Get to know Albert Einstein as a brilliant scientist, good friend and empathic physics teacher for the kids of Berlin. Find out more about the “German nuclear bomb”. Discover which role the physicist Werner Heisenberg played in the bomb’s development during the Nazi period, and why it was never made. Meet chemists Fritz Haber and Clara Immerwahr, who lived for their research and whose marriage ended in tragedy. Get to know imperial court architect Ernst Eberhard von Ihne, and find out why the research institutes he designed look like mansions.

‘The Walks’ is a collection of short audio experiences for special places in your city, as well as an invitation to rediscover and interact with your surroundings. Each audio walk takes just 20 minutes. Set out anytime and decide for yourself how many walks you’d like to take, and in what order. The stories and soundscapes in these short audio adventures resonate all over the world, and in that way, The Walks connects people around the globe in a local experience, bringing them together in the fundamental human act of walking. The pandemic changed the way we look at walking in public space. This ancient and mundane ritual became a central element of the new normal. People meet, walk, stroll through neighbourhoods, play in landscapes, and see their surroundings in new ways with every step. In ‘The Walks’, walking becomes a theatrical framework. An audio-guided walk in the park, a staged visit to the supermarket, or rhythmic aquatic interactions. In each city, voices, sounds, and music transform familiar places into scenes and landscapes into stages through storytelling, dialogues, choreographic explorations and musical and rhythmic variations of the humble walk. Each walk has a short title that indicates where or how it will be performed: “Cemetery”, “Water”, or “Roundabout”.
