San Gimignano rises, with the profile of its towers, on a hill that dominates the Val d'Elsa. For the characteristic medieval architecture of its historical center, it has been declared World Heritage by UNESCO. It had great development during the Middle Ages, thanks to the Via Francigena, that crosses it. Also today it is rich in history, art and culture, dipped in the green of the Tuscany campaign and surrounded by walls of the 13th century. San Gimignano is above all famous for the medieval towers that still stand out on its panorama. The most ancient it is the Tower of the Podestà, said the Rognosa, that is 51 meters high, while the highest is the Torre Grossa, 54 meters. The real towers are 14, (others are cut off), but usually in the computation we include the fifteenth tower, that is the bell tower of the Collegiata. The church, consecrated in 1148, said also simply the Cathedral, is considered one of the most prestigious examples of Romanesque architecture of Tuscany. It is enriched by valuable frescoes.
