Weissensee Abandoned Children's Hospital, Hansastraße 180, Berlin, Germany

Abandoned Berlin calls this a "zombie hospital," but you are unlikely to meet the walking dead here. Weissensee Abandoned Children's Hospital used to be a state-of-the-art medical facility during Germany’s Imperial Era. It now stands abandoned, strewn with graffiti, in a street where it is surrounded by modern apartment buildings. Visitors are warned that the hospital is a well-known spot for homeless people looking for somewhere to sleep and the building is very old and hazardous to explore.
