In Vienna, we're famous for our cozy gemütlichkeit. This may perhaps have even led to a very local architectural peculiarity: the "Durchhaus", or passage. It enables the cozy ones among us to get from A to B quickly and without detours. Quite incidentally, the passage was also good for a quick chat along the way. Which explains why today's Viennese complain about the volume of their neighbors with a slightly irritated: "This is not a Durchhaus!". However, the often hidden paths connect not only houses but entire streets. A total of about 700 of these Viennese short-cuts are scattered all over the city just waiting to be discovered.
