Once the highest mountain in Berlin, this manmade hill was made using the debris of the buildings bombed during the Second World War. Up until the Cold War, the hill was used as a Field Station of espionage, about what exactly? We won't know until after the records become public in 2020!

A little bit of a hike from the city center, you can visit this abandoned place which is now the largest graffiti gallery in Europe. You can take a tour of the place and see some of the most original graffiti ever, maybe you will even recognize some well-known street artists!
