Along the next part of the route, in the direction of Arezzo, there’s a mix of traffic passing close to the Ponte alla Nave, which was described in one of Leonardo da Vinci’s maps way back in 1502, when it was already an important structure on the road connecting the Valdarno and the Valdichiana. Near the Ponte alla Nave, the path is flanked by the Magazzino del Grano, built by the Order of the Knights of St. Stephen. This is where the Grand Duke’s army stored their agricultural products before it was sent to the market in Florence.
After about 60 km, the journey will start to wrap up as you come across one of the greatest and most impressive hydraulic structures in the area, the Chiusa dei Monaci. This water gate existed as early as 1115 and belonged to the monks at the Abbey of Sante Flora e Lucilla until 1797. The Chiana waters drove the mill where the monks made flour. Only much later was it supplied with sluice gates to regulate the water flow, and the current version has been there since 1839, based on a design by the engineer Alessandro Manchi.
This is where we end our journey. Arezzo is only 6 km away, so you can head on to the city or continue following the Canale della Chiana, which flows all the way to the Arno River. Here, you can also admire the Romanesque Ponte a Buriano, which is most likely the bridge seen behind the Mona Lisa in da Vinci’s great masterpiece.
