The Via delle Rocche starts from the hill of Montemurlo and its fortified village, the oldest part of the area, popular with Etruscans and Romans. Since the times of the domination of the Guidi family, the villa keeps the image of the fortress with the bulk of the ancient crenellated tower. Along the via Baronese, we plunge into gentle terracing that lead to the slopes of Monteferrato, where the amphitheaters of the former quarries of Serpentino or green marble of Prato are located.
The route reaches the pass of Collina di Prato and continues in the direction of the villages of Popigliano and Grisciavola until the ford of Vaiano, where the imposing complex of the Abbey of San Salvatore still stands.
We cross the Bisenzio river near the remains of the medieval bridge and we move to the side of the Calvana. The whole area is dotted with farmhouses and tower houses, among which the Torre di Melagrana stands. The building, located on the southern border of the Alberti's area of influence, had a purely military function, controlling the road network leading from one side to Montepiano and from the other to Mugello.
