This is the top view of the school Kasper goes to. It looks like an army camp from the sides too, it is not just the top. It is a huge concrete thing that has grades one to ten, high school is done at grade ten.
In its day it was considered a school of the future because it has everything. A swimming pool, gym, showers, cafeteria options rooms. It is great, but it still looks a little scary.
I do not know exactly how old it is but it had a 75 anniversary some years ago.
