Halensee is not a trendy district of Berlin, but rather a small, more middle-class neighborhood in the Charlottenburg-Wilmersdorf district. However, upon closer inspection, it reveals an interesting past and unusual places in the present. On this audio walk, we visit an island of the dead and the site where a haunted house once stood. We learn about Germany's largest brothel and the Berlin banking scandal. We stroll through the former Luna Park, discover what E. coli bacteria have to do with nudism, and hear the story of Berlin's mayor with the shortest term in office.
