It's a huge gray concrete thing with a concrete courtyard and actual bars on the metal gates. Every once in a while someone tries to partially paint it, but the gray concrete tints the colors and they become sad. Then it rains and the gray-yellow and gray-green and so forth become darker gray in long damp atmospheric drips. The classroom windows are plastic, and won't open, but the hallways are open and get flooded when it rains. There are plenty of stairwells open to a several floor drop. There is a somewhat bewildering metal statue of a bird. Sometimes PA class is held out back, outside, at the small cluster of trees that tilt east (?). It's won some architectural award.
