Stephansdom

St. Stephen's Cathedral 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 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. By the middle of the 12th century, Vienna had become an important centre of German civilization in eastern Europe, and the four existing churches, including only one parish church, no longer met the town's religious needs. In 1137, Bishop of Passau Reginmar and Margrave Leopold IV signed the Treaty of Mautern, which referred to Vienna as a Civitas for the first time and transferred the Church of St. Peter to the Diocese of Passau.
