|der Stadtturm, or "City Tower"|
"Im Jahre 1532 schlugen Bürger, Schmiede, und Bauern die Türken in die Flucht und erbautern zur Errinerung diesen Turm."
Which translates to:
"In the year 1532, townsmen, blacksmiths and farmers beat back the Turks and built this tower in their memory."
When I first read it I found to be a truly bad-ass message, although slightly incongruous with the Turkish kabob stand on the same block. Given the anti-immigrant fervor of Austria's far-right political party, I thought it might also make a passable campaign message.
