Found another 'oldie' at a secondhand-store. Vienna must be so wonderful, hope to go there one day!

At this card you can see: "St. Stephen's Cathedral by night".

St. Stephen's Cathedral (German = Stephansdom) is the mother church of the Archdiocese of Vienna and the seat of the Archbishop of Vienna, Christoph Cardinal Schonborn,OP. Its current Romanesque and Gothic form seen today, situated at the heart of Vienna, Austria in the Stephansplatz, was largely initiated by Rudolf IV and stands on the ruins of two earlier churches, the first being a parish church consecrated in 1147. As the most important religious building in Austria's capital, the cathedral has borne witness to many important events in that nation's history and has, with its multi-colored tile roof, become one of the city's most recognizable symbols.
