Crossing via de' Calzaiouli, you get in PIAZZA DEL DUOMO. Florence Dome has been realized by Brunelleschi in the space of 14 years, and finally consecrated in 1436 by pope Eugenio IV. On the side of the Cathedral, Giotto's bell Tower, 84 meters high, is dressed in white, red and green marbles to lighten the square. Here you are...the centre of the universe :)
