Stand in the square and read the facade like a book. Four monumental statues look down at you. The apostles Peter and Paul hold a key and a sword. Beside them are Salzburg's two patron saints, Rupert with a salt vessel and Virgil with a model of the church. High on the gable, two coats of arms commemorate the builders of the cathedral, Markus Sittikus and Paris Lodron. There are three doors, representing faith, love and hope, and the middle door of love is slightly larger than the others. Above you hang seven bells, each with a name, from Salvator, the largest, to Barbara, the smallest. Inside, the bronze baptismal font dates back to 1321 and was created by Master Heinrich. It rests on two lion figures that go back as far as the twelfth century, and its basin is decorated with reliefs of saints, bishops and abbots of Salzburg. This is the font in which Wolfgang Amadeus Mozart was baptized. Among the other things to discover are the crypt, the art installation called Vanitas, and the reliquary shrine with the remains of Saints Rupert and Virgil. The cathedral museum shows art treasures from 1300 years of church history.
