The interior, on the Latin cross plan, is divided into a nave and two aisles, with crossed vaults, separated by six columns each; the latter are in white or red Verona marble, with Gothic capitals. The four columns over the high altar show the coat of arms of the Castelbarco of Trento, a family who extensively contributed to the church's construction. Notable is the funerary monument to Cortesia Serego, on the left of the apse, which was finished in 1432 by Vincenzo di Stefano da Verona. It portrays the riding figure of Cortesia, clad with an armor and holding a commanding wand. His horse stands upon the sculpted sarcophagus, which has always been empty. The fresco part represents the Annunciation and the Saints Peter of Verona and Dominic.
