According to a nineteenth-century epigraph, placed at the top of the entrance gate, we read that the foundation of the building designated as the Oratory of the Disciplinants, datable to the sixteenth century, would have more ancient origins. The visible wall structure, with pictorial evidence recovered in the restoration begun in the eighties, do not allow to establish a construction date prior to 1200. A few fragments of fresco decorating the apse can be ascribed to the end of the XIII century, pertaining to the most ancient building. Over time, the building underwent extensions and alterations, among which the most notable took place in the seventeenth century, when the orientation was completely overturned, opening the entrance where originally the apse resided and placing the altar in front of the original entry door. It is possible to recover the narrative sense of the pictorial cycle, with stories of Christ and the Virgin, reappeared on the walls following the elimination of the various layers of plaster overlaid on the decoration between the late fifteenth and early sixteenth centuries.
