From Tardis Wiki, the free Doctor Who reference
Stephansplatz — was a central square in Vienna, Austria-Hungary.
It was the destination of Leopold Kraus when he was murdered. It was also the location of Stephansdom, to which Mary Shelley brought Cybermen Brem and Gram. The Eighth Doctor and Alfred Stahlbaum arrived there shortly thereafter in search of Mary. (AUDIO: The Silver Turk)
