On the walls there are two niche-styled altars that are built on each side and alternated to niches with statues. The apse is enriched by a wooden choir and preceded by a slightly elevated presbytery.
The high altar was executed between 1795 and 1796 by making extensive use, for the coatings, of marbles in various colours: ancient green, yellow from Siena and red from Verona. The building's neoclassical interior is characterized by a single nave covered with a vault with elegant pilasters and capitals reaching the cornice.
Among the furnishings, there is a quite imposing organ and two confessionals made of walnut; ther are canvasses and wooden sculptures of the 16th, 17th century and a gilded copper Cross from 1494 by Enrico of Piemonte.
The most important artwork is the Annunciation painted on canvas, dontated by Ippolito Borghesi da Sigillo and placed behind the choir.
