A huge prison right in downtown Chicago. That explains the tiny windows. This grand triangular structure, sometimes referred to as "the prism," is named the Metropolitan Correctional Center. It is a vertical prison, and supposedly has this shape in order to reduce the time needed to patrol its halls. This brutalist 70's design struck me as a very odd building, indeed. But who knew it was a jail? There is rumored to be an exercise area on the rooftop. Once again, to be able to get a size I want and as much in the shot as possible, this is 3 vertical images stitched together, and 3 exposures for each image.
