One of Europe's best building ensembles—Giotto's Campanile, the Cathedral of Santa Maria del Fiore and the Baptistery—load the centre of their dazzling walls of inlaid, Piazza del Duomo, colored marble eclipsing the buildings that encompass the square. The piazza and the connecting Piazza San Giovanni with the Archbishop's Palace, are neglected by a few monumental structures, including the Loggia del Bigallo, the Palazzo della Misericordia, the Palazzo dei Canonici, the Palazzo Guadagni, the Palazzo Niccolini, and the Museo dell'Opera del Duomo, where you'll locate the first show-stoppers that have been taken from the duomo complex to shield them from natural harm.
