Claim: Palazzo Gherardi is a 15th-century building with an austere  design and built with a series of square stone windows with grills and ten large, arched windows on the first and second floor.
Evidence: Palazzo Gherardi is a 15th-century building in the quarter of Florence, Tuscany, in central Italy. This notwithstanding, the design is sober, even austere, as is typical of XV century Florentine architecture. Along Via Ghibellina, at ground level, besides the doors, there are a series of square stone windows with grills. Both the first and second floors are marked by belt course and are almost entirely occupied by serried, large, arched windows, ten on each floor.
