The façade, typical of the Romanesque style, is about 24 meters high and outlines the width of the three naves. The upper part has three large arched windows whose horizontal shell constellation leads to a tympanum; the lower part is opened by three portals, one for each nave, and preceded by a portico, built by Carlo Fontana in 1702. Also originally the façade featured three arched windows, which were closed in the seventeenth century, and replaced with a large square one in the center and a circular one in the tympanum. The current form of the façade is owed to the Vespignani who, having destroyed all the windows, both those existing and those that re-emerged during the restorations, opened the three current arched sections, among which the Capparani realized his frescoes.
