The cathedral's façade will take your breath away, a masterpiece of design and sculpture by Giovanni Pisano, with a beautiful rose window and Venetian mosaics adding to the already colorful effect of green, red, and white marble inlay, which covers the building and its striking campanile. It is one of the finest achievements of Italian Gothic. Referring to Pisano's sculptures on the façade, the contemporary sculptor Henry Moore called him "the first modern sculptor."Almost the entire width of the façade is filled by three doorways of equal height, surmounted by pediments, with a slender tower at each end. Above the central doorway is a rose-window. Beautifully detailed sculptures decorate the remaining areas so harmoniously that it never seems overdone. To protect the original Pisano works from weathering, most were replaced by skillful copies in 1869, and the mosaics were added over the doors in 1877.
