We could have stayed at Camp Pirotte in Aachen (Germany) for hours. It's a perfect place for urban photography. Unfortunately, Koen had an appointment and so we left the former Belgian barracks. Just before departure, I took this picture. I could not resist. Of course I could not. Koen just had to wait.

I didn't see Koen for a while. He was outside, taking photographs to create a series of structures. I was inside and this window attracted my attention. Why did this building at Camp Pirotte need reinforced glass? It looked like a prison.

Bright colors are nice to shoot. Camp Pirotte Aachen did not have many bright colors. It was mostly gray. And gray. Until we ran into a wall, full of graffiti. Green, blue, black and white. The paint looked still wet.
