When you have a close look you can see a policeman with a shield and sword. In the eighties there were many riots in this neighbourhood in Amsterdam. The municipality wanted to demolish several houses in the innercity. But there was housing shortage and the so called "krakers" had occupied the houses to prevent demolishing. It caused a heavy confrontation between police and occupiers.
This sign is a remembrance of that time.
