Heaven's Gate is in the area called 'Kunstpark Ost', which was formally known for its manufactory of "Pfanni" - products like dumplings and purée. So you won't be surprised that a former potatoe silo has been converted into a climbing wall! Beginners can have a professional tutorial and the more advanced climber can enjoy the 32 meter high wall in a safe environment. After climbing, check out the rest of Kunstpark Ost which has several pubs and nightclubs.
