The Brunelleschi's Dome overlooking Florence and still there is no across the city's tallest building. The bell tower was designed by Giotto although did not see him over. The Baptistery is one of the oldest buildings in Florence and is there in the fourth century; with its magnificent gates is a true Bible in images. The Cathedral with its facade in white and green marble look. There is nowhere else in the world a complex of buildings so extraordinary. We are in the heart of Florence, opposite Santa Maria del Fiore, which everyone calls Duomo. A cathedral of 153 meters long, built in almost 170 years. Each tour of Florence starts from here: with their heads up and look in amazement, wondering how they made men create such a wonder.
