There is an internal dome over this choir, with a large open oculus but no lantern. The transparent covering over the dome was placed on June 7, 1991. The fresco in the dome is by Virginio Monti, and refer to the triumph of the Sacred Heart. At the base of the dome a blue band with golden characters reads: "Here every day my eyes and my heart". In the four pendentives of the cupola, Caesar Caruselli frescoed David and other prophets.
