It is therefore the seat of the Diocese of Székesfehérvár (Dioecesis Albae Regalensis or Székesfehérvári egyházmegye), which was created in 1777 by bull "In universa gregis" of Pope Pius VI.

The Late Baroque pulpit was built in a sumptuous classicizing style similar to Franz Anton Hillebrandt's main altar.

The sculpture group on the top of the abat-voix (Triumph of the Church over Idolatry) represents the same topic as the fresco on the first vault.

There is sculpted relief above the door with a group of symbols: the Eye of Providence, a horn, a violin, a wreath and a palm branch.

Idolatry is shown as a recumbent male figure, desperately grabbing a little idol, and an ancient bust had fallen on the ground behind his back.
