We all leave our footprints on the cities we grace. When you’re Audre Lorde, the 20th century’s most famous African American lesbian activist, your footprint leaves a longer trace. Follow the feminist writer’s last years in a new self-guided interactive tour, “Audre Lorde – The Berlin Years 1984 to 1992.” All you need is a smartphone, a data plan and then navigate to the mobile website. Once you’ve made it to a specific location, open the respective pin and get a handful of information, photos and sometimes soundclips about what the significance of the location was to Audre Lorde. No tour guide necessary, no tipping! The excursion boasts 38 locations, from the lakeside retreat of the Wannseeterrassen, which Audre often liked to frequent with her partner Dr. Gloria I. Joseph and friend and collaborator Dagmar Schultz (who also spearheaded this tour concept), to the main building of the Technical University, where Audre gave a seminal reading in 1984. Visit the Haus der Kulturen der Welt, where Audre delivered her provocative talk in 1988, which appeared in the book Power and Sensuality, alongside Adrienne Rich. Or, try the former Café April in Kreuzberg, now the vegetarian/vegan Cafe V, where Audre convinced the writer Ika Hügel-Marshall to write a book about her – which she eventually did.
