Säuglings-Kinderkrankenhaus Weißensee (Infant and Children's Hospital Weißensee) is an abandoned children's hospital in Berlin, Germany.
It opened in 1911, and initially treated up to 40 children.
I found the website in German, which says the hospital was once one of the most advanced medical facility in the country.
But sadly it was closed in 1997 for financial reasons and population decline.
This site had unique graffiti I had never seen in any other places.
Most rooms were with typical graffiti but there were rooms full of bananas, clouds, carrots, hearts etc...
Scroll down and you will see what I mean!
It was some dedicated work so I searched their signature "ONIGINAL" but couldn't find any information...
