About an hour ago I went home briefly. When I was almost there I heard screaming: "Turn around! On your knees!".
Fortunately it wasn't meant for me but for the guy that had some sort of an axe and was breaking the windows of the police station. I guess he was really angry, when I walked back to Chess I saw that at least 8 windows had been broken...
While looking for a nice picture of the police station I came across this (slightly sarcastic) article about the renovation of the Nieuwe Gracht, where Chess (my employer) is located. Translated: "It's always nice if big companies like Chess are able to see how people were living in the Middle Ages and how they transported their stuff over sandroads, with holes in the road. That must have given those smart guys a lot of inspiration".
The renovation this website talks about finished about a year ago but did indeed take much longer than expected.
