Monteriggioni is a living borgo held within a circular line of walls. Its main lane links Porta Franca, Piazza Dante Alighieri and Porta San Giovanni, making the village’s compact plan easy to read on foot.
Siena built the castle between 1214 and 1219 on Monte Ala. From here, the town watched the Via Francigena and the Elsa and Staggia valleys toward Florence, Siena’s rival. The Comune describes the wall line as following the natural shape of the hill.
The two gates still mark the route through the settlement: Porta Franca faces Siena, while Porta San Giovanni faces the Val d’Elsa. Sections of the walls were later buried against artillery, and towers lost in earlier centuries were rebuilt during major works in the 1920s and 1930s. The circuit therefore brings together medieval planning and later repair.
Piazza Dante Alighieri centres the borgo around the Pieve di Santa Maria Assunta, whose exterior retains medieval character. A separate ticket covers the wall walk and “Monteriggioni in Arme”; the combined ticket also includes the archaeological museum at Abbadia Isola.
