Westminster Cathedral
The site on which the cathedral stands in the City of Westminster was purchased by the Diocese of Westminster in 1885, and construction was completed in 1903. Westminster Cathedral is the largest Catholic church building in England and Wales and the seat of the Archbishop of Westminster.
St. Stephen's Cathedral, Vienna
In 1304, King Albert I ordered a Gothic three-nave choir to be constructed east of the church, wide enough to meet the tips of the old transepts. Under his son Duke Albert II, work continued on the Albertine choir, which was consecrated in 1340 on the 77th anniversary of the previous consecration. The middle nave is largely dedicated to St. Stephen and All Saints, while the north and south nave, are dedicated to St. Mary and the Apostles respectively. Duke Rudolf IV, "the Founder", Albert II's son, expanded the choir again to increase the religious clout of Vienna. On 7 April 1359, Rudolf IV laid the cornerstone for a westward Gothic extension of the Albertine choir in the vicinity of the present south tower. This expansion would eventually encapsulate the entirety of the old church, and in 1430, the edifice of the old church was removed from within as work progressed on the new cathedral. The south tower was completed in 1433, and vaulting of the nave took place from 1446 to 1474. The foundation for a north tower was laid in 1450, and construction began under master Lorenz Spenning, but its construction was abandoned when major work on the cathedral ceased in 1511.
In 1365, just six years after beginning the Gothic extension of the Albertine choir, Rudolf IV disregarded St. Stephen's status as a mere parish church and presumptuously established a chapter of canons befitting a large cathedral. This move was only the first step in fulfilling Vienna's long-held desire to obtain its own diocese; in 1469, Emperor Frederick III prevailed upon Pope Paul II to grant Vienna its own bishop, to be appointed by the emperor. Despite long-standing resistance by the Bishops of Passau, who did not wish to lose control of the area, the Diocese of Vienna was canonically established 18 January 1469, with St. Stephen's Cathedral as its mother church. In 1722 during the reign of Karl VI, Pope Innocent XIII elevated the see to an archbishopric.
