Located where Residenzplatz flows into Domplatz (where you'll see a 1771 statue of the Virgin), this cathedral is world-renowned for its 4,000-pipe organ. The original building from A.D. 774 was superseded by a late-Romanesque structure erected from 1181 to 1200. When this edifice was destroyed by fire in 1598, Prince-Archbishop Wolf Dietrich commissioned construction of a new cathedral, but his overthrow prevented the completion of this project. His successor, Archbishop Markus Sittikus Count Hohenems, commissioned the Italian architect Santino Solari to build the present cathedral, which was consecrated in 1628 by Archbishop Paris Count Lodron.

Hailed by some critics as the "most perfect" Renaissance building in the Germanic countries, the cathedral has a marble facade and twin symmetrical towers. The mighty bronze doors were created in 1959. The themes are Faith, Hope, and Love. The interior has a rich baroque style with elaborate frescoes, the most important of which, along with the altarpieces, were designed by Mascagni of Florence. In the cathedral, you can see the Romanesque font at which Mozart was baptized. The dome was damaged during World War II but was restored by 1959. In the crypt, traces of the old Romanesque cathedral that once stood on this spot have been unearthed.

The treasure of the cathedral, and the "arts and wonders" the archbishops collected in the 17th century, are displayed in the Dom Museum (tel. 0662/8047-1860), entered through the cathedral.

The cathedral excavations (tel. 0662/845295) are entered around the corner (left of the Dom entrance). This exhibition of excavation work shows ruins of the original foundation.

The allegorical play Everyman, adapted by Hugo von Hofmannsthal, is performed near the cathedral in Domplatz during the Salzburg Festival.
