The Church of St. Peter in Vienna is not the same in size as the eponymous San Pietro in Rome. It does not take the size, but rather follows the old Volkswagen advertising slogan "Small is beautiful!" The main feature of this church is the spectacular contrast of the narrow facade and the interior space. The narrowness of the facade is emphasized by the tiny area around. It is not known whose idea it was, whether it was Gabriel Montani, the first designer of the Peterkirche, or Johann Lukas von Hildebrandt, who led the construction since 1703. Passing through the narrow main entrance, you do not find yourself in a rectangular nave, as you expect, but in an oval one. A sense of spaciousness arises from properly organized lighting. The author of the dome is Matthias Steiner, the main altar is made by Antonio Galli da Bibiena and Martino Altomonte. The Baroque Church of St. Peter was built in 1701-1733 not from scratch. The previous church either burned down, or dilapidated and was demolished. Now the church is governed by the Opus Dei Order, about which Dan Brown wrote so much in his famous "Da Vinci Code".
