The church of San Barbaziano is a deconsecrated church in Bologna that stands at the intersection of Via Barberia and Via Cesare Battisti. It was built between 1608 and 1612 by Pietro Fiorini to replace the old church of the homonymous convent, now considered unsuitable for the new worship requirements defined by the Council of Trento. It consists of a single nave overlooked by eight side chapels (four on each side) some of which are part of the original church and incorporated into the new construction. Following the Napoleonic wars in 1797 the church and its convent were expropriated and sold to private individuals who transformed the church into a warehouse and stripped it of its contents. In 1870 the property passed to the military property which continued to use it as a warehouse, also building a loft to make better use of the space. Due to the long period of misuse, most of the decorations disappeared.
