In time, elements were added to the Jesuit Church to make it more prominent. But the true beauty and splendor of the church are within it. The architect Andrea Pozzo was appointed by Emperor Leopold to improve the interior of the church, as he did to many other churches in Vienna at that period. After the change he had made, adding colorful columns of the church covered with marble and gold, he gave the church a magnificent and imposing look. Beneath the dome of the church you can see the magnificent fresco, for which you will have to stand on the white flagstone, the only white tile on the church floor, and look up.
In the church gallery you can enter the Museum of Religious Art.
