The main church, which bears the date 1763 inscribed on its portal, stands almost against the castle walls and is bordered by the walkway known as “La Scarpa.”

This large building is the most important architectural element of the fortified nucleus: a fine example of Marche religious architecture from the second half of the 18th century, it significantly defines the inner square of the castle, opposite the Town Hall.

The interior has a Latin cross plan with a single nave. In the transept and side chapels, all the altars are different, richly decorated with columns, stuccoes, paintings, and statues. In the apse, in a niche crowned with stuccoes and gilding, there is a gilded wooden throne holding the image of the “Madonna del Soccorso” (early 18th century).

On the back wall, above the entrance, there is a balcony with a molded wooden railing, on which stands a beautiful late 18th-century organ.

Among the artworks, one can admire in the first altar on the right a painting signed by the Arcevia artist Ercole Ramazzani, titled “Crucifixion with Saints” (1596).

On the right transept altar, above a niche with a crucifix, there is a movable canvas by the important Roman painter Silvio Galimberti, depicting “Saint Michael the Archangel among other Saints” (1922).

Beneath the same altar, in 1985 (after the restoration of the Church of the Most Holy Annunciation), the urn containing the body of “Santa Teleucania” (19th century) was placed, along with the marble funerary epigraph and the paliotto that previously covered the body in the altar of the former church.

Other artworks include “Saint Gaudenzio” and “The Last Supper”, two canvases by unknown local artists (18th century), and two paintings by S. Galimberti: the “Sacred Heart of Jesus” (1918) and an “Immaculate Conception” (c. 1922) flanked by Saint Gabriel of Our Lady of Sorrows, Saint Aloysius Gonzaga, and Saint Tarcisius.

At the Baptismal Font: “Baptism of Jesus” (1940), a copy of the famous work by Andrea Verrocchio, created with the collaboration of his pupils, including Leonardo da Vinci, executed by Ciro Pavisa from Mombaroccio.
