Nowadays, Via Cassia does not correspond, at least the Tuscan stretch, to the ancient Roman road or even to the medieval route of the Via Francigena that ran along the Valdelsa. However, it was an important communication route that pilgrims and merchants from Florence traveled to reach Francigena in Poggibonsi.
Today, it starts from the Certosa del Galluzzo in Florence, the historic monastery founded in the fourteenth century and inhabited by a group of Benedictine monks from Circestensis. Important works of art are preserved here, including five lunettes with scenes of the Passion frescoed by Pontormo between 1523 and 1525 during his stay here to escape the plague that struck Florence.
From here, you reach San Casciano in Val di Pesa and then, continuing through the vineyards, Castello di Bibbione for a view from above of the Val di Pesa. Don't miss a visit to Badia a Passignano in Barberino Tavarnelle, the splendid fortified monastic complex, and to the Castle of Tignano.
