In 1729, Filippo Juvarra adds an apsis with an hexagonal plan aimed to contain the big altar. Above the apsis, an elliptical dome that ends with a little lantern. A big continuity between the two architects can be detected, as if Juvarra wanted to develop the idea of Guarini. The road to the apsis is marked by steps that separate the different halls and enhance the scenographic setting of the altar. It is a very sumptuous altar, one of the most impressive of Juvarra: marble columns and golden rays surround the portrait of the Madonna surmounted by a dome-shaped canopy.
