........./Justice%20and%20Detention%20Centre

This is the Justice and Detention Centre (i.e., court building and penitentiary) in Leoben, Austria.  Designed by architect Josef Hohensinn, Austria's "show-piece prison" was built to house inmates
in circumstances described as follows:

     Prisoners in groups up to thirteen are accommodated in a
     wing of their own and can move freely among the cells and
     communal spaces. The architect suggested the additional
     possibility of stepping out for fresh air, so it was
     agreed that each communal section would have a kind of
     outside area surrounded by bars, of course, but the
     inmates are outdoors.  The prisoners also have three
     courtyards at their disposal, with concrete seating
     walls meandering through the space, so it would no longer
     be possible to circle around in a single file.
