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.

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.

The underside of the abat-voix is decorated with a dove, and there is a sculptural group on the top depicting the Triumph of the Church over Idolatry.

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.
