Upper left: Part of the office building complex in which the Institute for
Theoretical Physics (ITP) is located, as seen from "Prager Strasse" (where
you can enter through a door hall next to a water bed store, passing the
yard and then taking the elevator to the offices of the ITP in
the 1st and 2nd floor).
This view is basically what you will see from the tram stop at "Ostplatz".
Lower right: View from the opposite side of the building from "Vor dem Hospitaltore", considered to be main entrance to the Institute.
