St. Stephen's Cathedral, Vienna
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.
