a high-rise flat building. There are many buildings like this one (I wasn't able to get a whole house on the photograph) together. They're called "Folsterhöhe". It's like a little town there with a school and some stores between the houses.
because I don't like carnival I went for a walk with my camera to take a lot of new photos to show you the next days. Today you get a picture of a bus stop located in a pretty quiet quarter of Saarbrücken =)
