San Gregorio Magno is a Roman Catholic church located in the town limits of Mogliano, province of Macerata, in the region of Marche, Italy.
Founded in the 10th century, it originally was a church that was extra moenia, thus outside of the castle walls.
But the major change started circa 1714 by Gianfilippo Carnili, when the orientation of the church was inverted from the Romanesque dogma of western façade and eastern apse, in order to accommodate a scenographic entrance from the street.
This construction was completed in 1748 and resulted in the present brick façade with pilasters and a rounded tympanum, an elegant white stone portal, and preceded by an elaborate two flight, staircase with white balustrades.
