The most elaborate facade belongs to the 1563 Palazzo Lomellino . The grey blue exterior is festooned with stucco adornments, while the internal courtyard is dominated by an 18th-century nymphaeum (monument to the nymphs). Upstairs, the remarkably preserved 17th-century frescoes by Bernardo Strozzi were only uncovered in 2002, after languishing for almost 300 years above a false ceiling. They depict allegories of the New World, in homage to the palace’s one-time owners, the Centurione family, who financed Columbus’ voyages.
