The Arco di San Benedetto is an arch built by the Benedictines in 1704. According to legend, it was built in one night to defy a city ordnance against its construction on the grounds that it was a seismic liability. On the left past the arch is the imposing Chiesa di San Benedetto, built between 1704 and 1713. Inside is some splendid stucco and marble work.
