This is perhaps the most visited places in Europe and in Florence, the most favorite tourist’s area of the city. The square contains the Florence Cathedral with the Cupola del Brunelleschi, the Loggia del Bigallo, the Florence Baptistery, the Giotto's Campanile, the Opera del Duomo Museum, and the Arcivescovile and Canonici's castle. This late Gothic pubic loggis is connected to two altruistic organizations. The first, Compagnia della Misericordia, or "Organization of Mercy", dealt with orphans by sheltering them at the loggia; the second,Compagnia di Santa Maria del Bigallo, really focused on pilgrims and travelers. Situated on the side of the piazza of the Duomo and by means of Calzaioli, the mid-fourteenth century Loggia del Bigallo has been a small museum since 1904. Indeed, even from outside, you can respect the frescoed fabricating, however heading inside will allow you an opportunity to see the much decayed yet famous fresco of the Madonna della Misericordia, a picture of the Virgin Mary with her cape encompassing her devotees (in this case the whole city) who are surrounded under and around her. The Bigallo Madonna is portrayed with the oldest known perspective on Florence.
