Begun in 1296 in the Gothic style and completed in 1436, The Basilica di Santa Maria del Fiore is Florence’s beautiful cathedral and symbol of the city. The exterior of the basilica is faced with polychrome marble panels in various shades of green and pink bordered by white. The basilica is one of Italy’s largest churches, and until the modern era, the dome was the largest in the world. It remains the largest brick dome ever constructed.
