With its majestic façade, Palazzo Sordi stands at 23 Via Pomponazzo. The bright colours, illuminated by an excellent restoration, bring out the size of the building - the product of the genius of the Flemish architect Frans Geffels (1625-1694). The façade is dominated by an additional, central floor, which corresponds to the reception room. The ashlar-work is alternated with smooth surfaces, while the doorway is adjoined to a marble balcony. Above this balcony, on the inside of a tympanum enriched by refined faux capitals, there is a tondo displaying a beautiful Madonna and Child, the hand of the stucco worker of the Val d'Intelvi, Gian Battista Barberini.
