I just share a little info about this famous and beautiful Cathedral in Vienna..courtesy of Wikipedia..if you want to know more about it, please visit Wikipedia for more info!!
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 Schönborn, 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 born witness to many important events in that nation's history and has become one of the city's most recognizable symbols.
